A convicted murderer who stabbed an Eastside woman 18 times in the parking garage of the Gateway office building in Kirkland November 2009 pled guilty to attempted first-degree murder Monday.

Patricia Lynn Crowl, 50, who previously served nine years in prison for murder and was released in November 2006, will be sentenced Dec. 10 for the stabbing of Jaime Checkos. Crowl now faces 20 years in prison.

Both incidents were reportedly in response to jealously over a boyfriend.

Checkos, 29, was the former girlfriend of a man Crowl was dating last November. The attack was sparked by texts that Crowl found between Checkos and the man. The victim, who has a daughter, suffered a punctured lung and many other injuries as a result of the attack. Crowl lured Checkos to the Kirkland building through text messages.

After the attack Checkos dialed 911 from her cell phone. She told the dispatcher that she had been “stabbed everywhere,” and that “she was dying,” according to court documents.

Crowl murdered Shawn Wallace, who was six weeks pregnant,in 1997 by beating her with a wrench in a jealous rage. The rage was sparked because the woman was dating Crowl’s then boyfriend. Crowl served the full nine years of her sentence for the murder. The courts deemed her to not be mentally ill and she served two years of probation with no violations.

Crowl was not the only person involved in the events of the murder. After Crowl hid Wallace’s body under her house, she decided to move the remains to a dead-end road in Tukwila with the help of her ex-husband, Jonathan Adam Henry. Henry was convicted of first-degree rendering criminal assistance and sentenced to six months in jail.
