WINTER HAVEN — A 23-year-old Lake Wales woman was shot in the shoulder Monday in a case in which her ex-boyfriend's roommate thought she was a burglar, Winter Haven Police said.

Trekeria Richardson was pushing on the door with her shoulder when Joshua Peguero, 26, fired a shot through the door, hitting her shoulder, police reported.

Richardson underwent surgery for injuries that were not considered life-threatening at Lakeland Regional Health Medical Center, officials said.

About 11:45 p.m., Peguero and Danzil Norman, 25, who both live in Briarcrest Apartments at 200 Ave. K, SW, Apt. 64, heard someone push on the door and wiggle the door handle.

Peguero told police he was on edge because the apartment had been burglarized three times in the past two months.

He grabbed a handgun and waited by the door.

Norman had been having issues with Richardson, his ex-girlfriend. On June 18, after their breakup, Richardson was charged with breaking into Norman's car and damaging his phone and car, said Jamie Brown, a spokeswoman with the Winter Haven Police Department.

Norman looked outside to see whether he saw Richardson's car in the parking lot. When he didn't see her car, the two decided to unlock the door to confront the person at the door, police said.

Norman unlocked the door with Peguero ready to fire his pistol, police reported.

When the door was unlocked, it pushed forward until a second lock caught the door from opening, police reported.

Peguero fired one shot, striking Richardson in the shoulder as she pushed against the door.

The men realized it was Richardson who had been shot and began to help her until officers and an ambulance arrived.

No charges have been filed, but police continue to investigate.

Brown said detectives want to talk to Richardson again about the timeline of the incident.
