King County prosecutors have filed charges against David Haggard, the older half-brother of Jamie Haggard, a mother of two who went missing in 2016 from their home on the Kenmore-Kirkland boundary.

On Oct. 28, charges were filed against David Haggard for second-degree murder and bail is set at $2 million. He was already in custody for an unrelated 2016 arson charge that is currently pending trial.

The King County Sheriff’s Office (KCSO) investigation began on June 17, 2016, after Jamie Haggard, who was 27 years old, was reported missing by her father.

During the investigation, KCSO said witnesses told major crimes detectives that Jamie Haggard had a “volatile relationship” with her half brother and more than once said she worried he’d kill her.

Probable cause documents state that David Haggard had threatened to kill his sister and assaulted her more than once. Friends reported seeing ligature marks and bruises multiple times on Jamie Haggard. According to these documents, both were methamphetamine and heroin addicts.

In the days leading up to Jamie Haggard’s murder, she and David Haggard allegedly argued about the house — which did not belong to either party — and who should be allowed to stay there. David Haggard’s girlfriend and another man also lived with the siblings.

Shortly before Jamie Haggard disappeared, a disagreement between the half siblings led to David Haggard knocking Jamie Haggard out, a KCSO detective wrote.

On June 7, 2016 David Haggard and another house member kicked Jamie Haggard out of the home, on the grounds that they believed she had stolen from them. David Haggard later admitted to police that he had slapped Jamie Haggard while on top of her when she returned home on June 8, 2016.

Jamie Haggard told her boyfriend, who was in jail at the time, that she felt her half brother would kill her, charging papers state. Jamie Haggard had planned to pick her boyfriend up after he was released from jail on June 10, 2016.

Recorded phone conversations between the two continued on June 8 and 9, 2016. Again, Jamie Haggard said her brother tried to kill her and punched her in the face on her right cheekbone and in her abdomen“as hard as he could.”

Jamie Haggard told her boyfriend she planned to return to the Kenmore home, where she was going to tell her brother he had to leave or she would call the police, charging papers state.

Detectives estimate that this phone call took place 20 minutes before Jamie Haggard walked into the home at about 8:45 a.m. on June 9, 2016. She again spoke with her boyfriend for 15 minutes while at the home. She promised to pick him up the next day. She never showed.

The last time anyone heard from Jamie Haggard was on June 9. Her laptop and pain medication, which she would typically take with her, remained at home. Jamie Haggard’s cell phone was also located at the house.

On July 15, 2016, investigators showed up to her home on the Kenmore-Kirkland boundary with a backhoe, hoping to find clues in what had turned out to be a month-long missing person case. Another tip-prompted dig happened a year later, in May 2017. But still, Jamie Haggard was not found.

On May 10, 2018, a Snohomish County litter cleanup crew found Jamie Haggard’s partial-burnt and dismembered remains in a suitcase off the shoulder of Downes Road. The spot was north of the Golf Club at Echo Falls along Highway 22.

At the time of discovery, investigators were unable to confirm the gender of the body, given its decomposing state. The body was confirmed and identified as Jamie Haggard in July 2018.

The remains were wrapped in a fitted bed sheet, a black garbage bag, construction wrap and clothing fragments. Cell phone pieces were also in the suitcase, and what appeared to be what remained of a burnt red sheet or pillowcase.

A house member later told detectives that his red sheets were missing, and identified the scraps from the suitcase as his own. Others confirmed that David Haggard had access to construction wrap.

When police moved toward doing a polygraph test, David Haggard allegedly told others that he wouldn’t pass. A search warrant later revealed that on June 14, 2016, a stolen car David Haggard was allegedly driving traveled on a route near where Jamie Haggard’s remains were found.

The defendant had also set two previous fires to conceal evidence. Appliances from a mobile home in Duvall and forklift used to transport a welder to David Haggard’s truck were both set ablaze.

His arraignment hearing is planned for Nov. 7, in King County Superior Court.
