Gainesville police on Tuesday had no answer to what prompted a woman to fatally shoot her former boyfriend in the head in her apartment on Monday.

Katherine Jean Tonner, 24, remained in the Alachua County jail on a murder charge for the death of Jose Ricardo Ortiz III, 26.

A motive for the shooting in her apartment at the Ridge complex at 3801 SW 22nd Place has not been released.

“It still under investigation,” said GPD spokesman Officer Ben Tobias. “There’s nothing new and I don’t expect anything anytime soon with it.”

Tonner called 911 at 12:38 p.m. and reportedly told the call taker that she was at her parents’ home, was suicidal and had shot a man who had been badgering her for money. She reportedly told police he was dead.

Ortiz’s body was found by one of Tonner’s roommates. A police report said Ortiz had been living in the apartment despite the split.

The roommate told police he was in his third-floor room when he heard "three loud bangs" below him on the second floor. About five minutes later, he heard a fire alarm and went to investigate, the arrest report said.

He didn't see anyone in Tonner's room, but smelled a burning odor and saw her car driving away. He then checked again and saw Ortiz face down on the floor near Tonner's bed.

The roommate called 911 and told officers he heard no arguing — despite "paper-thin walls" — before the shooting, police said.

GPD has not released the 911 recording of Tonner’s call. The report states the dispatcher advised Tonner to put the gun in a drawer.

An Alachua County sheriff’s deputy went to Tonner's parents' home and Tonner made a number of spontaneous statements, including "I shot him in the head" and "I never meant to hurt anyone," the report said.

After getting a search warrant for her parents' home, police found a loaded .45-caliber semi-automatic handgun in a kitchen drawer, the report said.

Tonner didn't say who she'd shot, only that she loved him, police said.

Police remained outside the apartment throughout the day Tuesday. Other residents declined to talk about Tonner, Ortiz or the incident.

Both Tonner and Ortiz spent at least part of the their school years in Gainesville.

Alachua County Public Schools spokeswoman Jackie Johnson said Ortiz graduated from Buchholz High School in 2008. Tonner attended Kanapaha Middle School until the eighth grade. She was no longer in public schools in the county after that, Johnson added.

Tonner worked as a clinic assistant at Southeastern Integrated Medicine. Her father, Dr. William Tonner, is a physician affiliated with the complex on Newberry Road.

In 2006 Tonner had filed a complaint with police alleging Ortiz, who she described then as her former boyfriend, had stolen several items from her and pawned them. Tonner discovered the pawn receipt as she was moving some of her belongings, the report states.

Ortiz reportedly told Tonner he took the items because he was low on money. Taken were a Nikon Coolpix camera, an external storage drive and an Altec portable speaker.

Tonner told authorities that she wasn’t certain she wanted to report the theft but that she wanted the items back, the report states.
