King County prosecutors plan to charge a man with first-degree murder after the death of a 17-year-old girl he allegedly stabbed a week ago in Redmond.

Daniel J. Haggart, 25, is accused of stabbing an acquaintance, Cara A. Neil, 17, on July 18 outside Soul Food Books, 15748 Redmond Way, while he was fighting with his girlfriend.

He was initially charged with first-degree attempted murder.

Neil died Wednesday night at Seattle’s Harborview Medical Center from a stab wound that punctured her heart, according to the Redmond Police Department.

The initial charge against Haggart will be amended to first-degree murder Friday, said Dan Donohoe, spokesman for the King County Prosecutor’s Office.

The stabbing stemmed from a fight Haggart was having with his girlfriend last Friday, according to charging documents.

The girlfriend showed police text messages she claims he sent her less than 10 minutes before the stabbing, the charges alleged. One message said “if you don’t call me I’m stabbing the first person I see,” charging papers stated.

The girlfriend told police Neil had angered Haggart when Neil came to her defense during an argument the couple were having outside the bookstore, according to charging papers.

The girlfriend told police that at one point Haggart walked away from Neil in anger, and Neil called him a “bitch,” the document states.

The charging documents are not clear on what happened next. But the girlfriend told officers she saw Neil collapsed on the ground, the charging papers state.

Redmond police responded at 10:50 p.m. and saw four people gathered around the bleeding Neil. Police said Haggart was among the people who came to the wounded girl’s aid when they arrived, according to court documents.

The officers said Haggart was shirtless and covered with small gashes that he told police were self-inflicted with a knife, the charging papers state.

When an officer approached him to document the scratches, he spit “a significant amount of saliva” in the official’s face, according to charging documents.

Police recovered a knife with a 3-inch blade that appeared to be bent and covered in blood next to Haggart’s wallet, keys and hat, the charging documents said.

Police spoke with several witnesses to the attack, including friends of both Neil and Haggart, and employees and patrons of the nearby businesses, according to court documents.

Haggart has a long record of past offenses, including afelony conviction for trafficking in stolen items and juvenile felony convictions for assault. He also has a long history of misdemeanor convictions for assault and theft.

Haggart was originally held in the King County Jail in lieu of $750,000, bail, but the amount was amended to $1 million when it became clear Neil would not survive the attack, court documents said.
