2018 WHIA Program

WHIA 2018

Annual Educational Conference

and Vendor Expo
May 8 - 11th, 2018

Welcome
Welcome back to the Clearwater Resort and Casino for our
sixth Annual Washington Homicide Investigators
Conference. We've selected several presentations that focus
on lessons learned. Over the next two and a half days, you’ll
hear about a variety of cases that will provide a full spectrum
of investigative challenges, problems, and responsibili-
ties. I'd like to thank our featured presenters and their agen-
cies for candidly sharing their experiences.

The last year has been marred with a continuation of an alarming trend; mass
shootings. Recently, the United States has witnessed the worst mass shootings
in our history; Las Vegas and Parkland, Florida to name two. Both incidents
sparked continued national debate. While I believe it's prudent for investigators
to stay out of the political fray, we cannot put our heads in the sand and pretend
a tragic event like this can't happen in our communities. The question then be-
comes, do you and your agency have the system in place to deal with a mass
shooting or incident that completely taxes your resources? The time to plan for
a major event is now; not when it happens. Take advantage of the breadth of
knowledge and experience you'll find at this conference and ask tough ques-
tions, share ideas, and get to know your neighbors.

On a lighter note, based on your feedback we have made some subtle changes
(hospitality, menu, vendors) to this year's conference that should make it a bet-
ter experience for all. We constantly strive to make this a
premier event so as always, keep those great ideas coming.

On behalf of the Executive Board, Advisory Board and Planning Committee,
welcome to the 2018 Washington Homicide Investigators Annual
Conference and Vendor Expo.

Special Guest of Honor

Officer Michael McClaughry
(Retired)
Mount Vernon PD

2017 Recipient of
the
Washington State
Law Enforcement
Medal of Honor

Retired Officer Michael McClaughry was hired by the Mount Vernon Police
Department in May of 1985. During his career, Mike’s various assignments
included the Department’s first DARE Officer, sketch artist, Criminal Investiga-
tor, Lead Officer, and Field Training Officer. As an FTO, Mike was either the
primary trainer or had a hand in training a majority of the current MVPD Offic-
ers. Mike has been actively involved in the Boy Scouts for more than 15 years,
mentoring numerous future leaders through Eagle Scout projects. Mike has been
a role model for officers and citizens alike.

On December 15, 2016, Mike was investigating a reported shooting in the
City. As Mike and other Officers approached the front door of a residence,
several shots were fired from inside; one round striking Mike in the head. Mike
was ultimately airlifted to Harborview Medical Center where he remained for 59
days. Mike is now blind, has undergone multiple surgeries, and continues in a
lengthy recovery period. Throughout, Mike has been an inspiration to everyone
around him, focusing on how to “live and love life” and what he can do rather
than dwell on what he can’t do.

Mike is a recipient of the Washington State Law Enforcement Medal of Honor,
Mount Vernon Police Department’s Purple Heart, and the Boy Scouts of Ameri-
ca North Star Award.

On December 1, 2017, after 32 and a half years of service, Officer Michael

Lead Investigative Agency: Washington State Patr ol

Case Description Summary:
On April 16, 2017, Easter Sunday, Stanley Wayne Christopher was located de-
ceased after being struck by a vehicle that fled the scene. Three days later the

sonal physician, Dr. Conrad Murray was found to be responsible. He was
charged, tried and convicted of involuntary Manslaughter.

Learning Points / “Lessons Learned” Topics:

Double Murder in Belltown

Suspect(s): 47-year-old Raymond Sanchez, basically no prior
criminal history.

Victim(s): 65-Year-old Larry Humphrey &
his domestic partner, 58-year-old Holger Spippach

Lead Investigative Agency: Seattle Police Homicide Unit

Case Description Summary: Seattle Police r esponded to the Bell Tower Apar t-
ments at 2216 1st Avenue to check-the-welfare of the resident of unit #1609. Caller
Donald Richardson reported to 911 that he had not 911 call to check the welfare of the
resident of 2215 1st Ave #1609. Per the caller, Mr. Donald Richardson, the tenant, Lar-
ry Humphrey, had not been heard from for two or three weeks. The officers knocked on
the apartment door and there was no answer from within. A building maintenance em-
ployee then opened the door with a master key. Officers entered and found the bodies of
two badly decomposed bodies that clearly been the victims of extreme homicidal vio-
lence.

Learning Points / “Lessons Learned” Topics: Analysis of steps taken to conceal the
crime scene and the challenges that posed, high importance of thorough crime scene
processing, the victims’ high risk lifestyle and traffic in and out of the apartment made
it difficult to identify persons of interest and/or evaluate surveillance video evidence,
the circumstances of the delayed DNA identification of the suspect, the challenge of
locating the suspect on the other side of the country, importance of learning as much as
possible about the suspect prior to interviewing him and how what was learned about
him proved critical to his confession.

Sportspage Tavern Triple Homicide

Suspect(s): Cleanthony (Big Cle) J imer son

Victim(s): Lor enzo Duncan (23 year s old at time of death)
Nicholas Lindsay (26 years old at time of death)
Antuan Greer (21 years old at time of death)

Lead Investigative Agency: Aubur n Police Depar tment

Case Description Summary: On the evening of Mar ch 31, 2013, the Spor tspage
Tavern was at capacity with patrons to include two groups there for different celebra-
tions, one of which was the Jimerson family. As patrons started leaving at 0200 hrs, a
fight broke out near the front doors over two girls and an ill-advised dance. Those in-
volved moved through the parking lot, causing several other fights. One person began
shooting in the air to stop the fights, which prompted others to get their own
guns. Within seconds, there were six people shooting, people scattering everywhere
within a packed parking lot, resulting in four people shot, three of which were pro-
nounced dead at the scene. Officers stopped two cars leaving the scene, both with iden-
tified shooters and two recovered guns. Two other guns were located at the scene, but
two guns were missing and never recovered, including the homicide weapon. Patrol
officers struggled to maintain control of a large parking lot, while family and friends of
deceased tried to pushed in. Over 100 witnesses were contacted, most refusing to coop-
erate or provided conflicting information.
After a seemingly hopeless start, three years later a suspect was arrested only to result in
two contentious trials where he was finally found guilty of two counts of Murder 2nd.
Learning Points / “Lessons Learned” Topics: Don’t give up. Work as a team when
reviewing evidence and lab results. Even uncooperative witnesses can provide critical
information to the case. Have a plan when interviewing a suspect. Don’t give defense
attorneys your opinion of what you believe happened even when they ask

Matricide: The murder of Judy Hebert

Suspect(s):
Tashia Stuart

Victim(s):
Judy Hebert

Lead Investigative Agency:
Pasco PD, Franklin County Prosecuting Attorneys Office

Case Description Summary:
The case starts with 911 hang up call where only after ob-
taining a recording of the call can you hear one of the 3 gunshots. Upon return call to
residence, smoke alarm is going off in background and defendant tells dispatcher that it
was caused by a need to change the battery. Initial officer responds as non priority hang
up call. Neighbors call asking about sounds and checking on mother as it was known to
friends of the deceased that mother and daughter did not get along but mother wanted to
see her 8 year old granddaughter so tolerated her coming back to live at the house with
her husband only about 6 weeks before the homicide.
The case turns out to involve an earlier attempt on the victim with a plot to lure mother
into garage with ruse of remodeling work. Daughter pushed a 30lb bin of books onto
her mother’s head and they keep her in home believing she may die of injuries in a few
days. A search of defendant’s phone obtained during homicide investigation reveals a
video of an attempt to crack the mother’s personal safe located in her master bedroom
closet. The cell phone video captures defendant daughter trying to place the phone in a
position to capture the security code on the safe. Located in the home is a sketch of the
garage with a mark indicative of where the book bin would drop. Copies of various
wills are located in the bedroom where defendant and husband stayed. Money appears
to be strong motive.
Additional evidence on the phone includes website searches of how to safe crack, seal-
ing materials that could be used to cover up the crime of dropping the books in the gar-
age. Various statements to neighbors and to loving ex-husband and father of defendant
including attempts to get the ex to give up the safe combination.

Learning Points / “Lessons Learned” Topics:

Details matter; primary focus on the homicide investigation sidetracked a little from the
investigation on the earlier attempted murder that occurred 10 days earlier. A prosecutor
and investigator perspective will address the challenges faced at trial; what could be
done differently in the investigation to change the outcome of court rulings and/or
strengthen other areas of the case. How to address young key witnesses and the pros and
cons of having them testify.

State vs. Ivanov – Mass Shooting at a Teenage
House Party

Suspect(s): Allen C. Ivanov – 19 years old

Victim(s):
Anna M. Bui – 19-years-old – Deceased
Jordan M. Ebner – 19-years old – Deceased
Jacob M. Long – 20-years-old – Deceased
William A. Kramer – 19-years-old

Lead Investigative Agency: Mukilteo Police Department

Case Description Summary: On July 30th, 2016 a warm summer night in a sleepy
bedroom community was forever shattered by gunfire. Three innocent young peo-
ple were gunned down in cold blood at a house party. Earlier in the day, Anna Bui
told ex-her boyfriend, Allen Ivanov, that she did not want to rekindle their ro-
mance. Ivanov broke off their relationship several months earlier because he
feared that Anna was losing interest in him. Now he was desperate to win back his
“dream girl.” Ivanov was jealous and convinced that Anna was seeing other men.
He had purchased a Ruger AR-.556 a few days earlier with the intent of making
Anna and her friends “pay.” Anna’s final rejection appears to be the trigger
event. Ivanov showed up at the party, surveilled it, and then murdered Anna Bui,
Jordan Ebner and Jake Long and shot William Kramer. Ivanov’s internet search-
es showed that he had been planning a mass shooting for at least two weeks, and
his intent was carnage. Ivanov was arrested by Washington State Patrol Troopers
in the Chehalis area as he fled south after the shooting. This was not a whodunnit,
but instead an exercise in building such a persuasive case that had the county pros-
ecutor wanted to, the state could have won a death penalty case.

Learning Points / “Lessons Learned” Topics:
It’s all about teamwork; detectives, prosecutors and outside agencies
We work for the victims and their families, set ego aside
Case detectives should contact the victim families as soon as possible to devel-
op a relationship; they will exhaust you, but will also be your allies
For a small agency, close ties with other local police agencies is critical
Make sure your patrol supervisors are up to date on case law - phone pings
The first 24 hours was critical, make sure you are fueled up and ready to go.
Take a break to eat and clear your mind to keep up your strength
