Pierce County prosecutors on Monday charged two more people in a Feb. 16 shooting near Frederickson that left a 24-year-old man dead.
One of them, Presley Diane Lind, 28, pleaded not guilty to first-degree murder, second-degree murder and unlawful possession of a firearm.
Superior Court Commissioner Meagan Foley ordered Lind jailed in lieu of $1.5 million bail.
Also charged with murder was Christopher William Olsen, 32.
Olsen, who is suspected of firing the shot that killed Robert Ward, was arrested in Post Falls, Idaho, on Saturday and was being extradited to Tacoma, Pierce County deputy prosecutor Phil Sorensen said.
According to charging papers, Nathan Stevenson, Lind and Olsen conspired to lure Ward to a parking lot near 176th and Canyon roads.
Stevenson later told investigators the real reason for the meeting was to recover a 2009 Toyota Corolla that Ward allegedly had stolen, court records show.
But Stevenson allegedly told Ward a man named "Chris" was interested in making a heroin deal and would be there, the records state.
"Stevenson said he knew that Lind and others intended to take the car from and assault Ward," prosecutors wrote in charging papers.
Stevenson has pleaded not guilty to murder charges.
When Ward arrived, Lind allegedly parked her car in front of the Corolla while Ward parked a rented pickup he was driving behind it, court records show.
Lind then walked up to the Corolla and told two people riding with Ward they might want to get out of the car, the records state.
Ward then drove off with the pickup in pursuit.
"Shots were fired from the truck and struck Ward," prosecutors wrote in charging documents.
Lind, who lives in Olympia, later told detectives her only interest "was to help Olsen get his belongings back," the records state.
Olsen declined to make a statement to law enforcement when he was arrested.
