A suicidal woman who was shot and killed in a standoff with Lawrence police Sunday afternoon left a note behind and was having personal, medical and financial problems, police said this morning.

“I am sorry to conclude that this was the outcome she desired,” Police Chief Ron OIin said in a morning news conference.

An officer shot and killed Marsha Lynn Mace, 36, at 1:23 p.m. Sunday after a roughly 4-1/2-hour standoff at trailer No. 107 at 110 N. Michigan St.

In the moments before the shooting, Mace emerged from the trailer holding a small revolver and fired at two LPD officers, Olin said. One officer returned fire, he said.

She was flown to a Kansas City hospital with two gunshot wounds, and police announced this morning that she had died.

“We do have, on the scene and through our preliminary investigation, personal, medical and financial reasons for her depression,” Olin said. “We extend our condolences to the family and to the officer’s family.”

Police have not yet identified the officer who shot Mace. Olin said that officer was interviewed Sunday evening and has been placed on administrative leave, pursuant to the department’s policies.

“The preliminary information… clearly indicates that this was not caused by anyone but the victim, and that the officer took the actions he should have at the time that he took them,” Olin said.

The standoff began shortly after 9 a.m. Sunday when an officer went to the trailer at the request of Mace’s mother, who was concerned about her well-being. When the officer knocked on the door, Olin said, there was a gunshot from inside the trailer.

The officer sought cover at his patrol car and called for backup. Officers tried to contact her through a public-address system, and she was “despondent” when an LPD captain reached her by cell phone, Olin said. Eventually, three negotiators were called to the scene and negotiated with Marsh for about an hour and a half.

About 12:30 p.m., there was a second shot from within the trailer, Olin said, but negotiators at that time remained in contact with Mace and knew that she wasn’t harmed.

Olin said he could not yet give the exact number of shots fired, by whom, and when, and that witnesses are still being interviewed. The Kansas Bureau of Investigation and LPD detectives were still investigating the crime scene as of this morning, Olin said.

“The investigation is not complete,” he said.

The last shooting involving Lawrence Police was in November 1995, Olin said. In that case, two detectives exchanged fire along the Kansas River with a suspect in a bank robbery and carjacking. One officer was injured in the shooting, and the suspect suffered two gunshot wounds before turning his gun on himself.

City commissioner Sue Hack, who attended Monday’s press conference, said she and other commissioners had been briefed on the shooting. She said she was confident it was handled properly.

“It’s a sad day,” she said.
