A Baton Rouge man accused of breaking into a couple's Robbie Avenue home in September and firing a single fatal shot to the victim's forehead while he was in bed sleeping with his wife has been arrested.

Thadius Brothers, 24, 3003 Toronto Drive was booked Wednesday with first-degree murder, aggravated burglary and illegal use of a weapon by Baton Rouge police in the Sept. 30 killing of 37-year-old Robert Winfield, parish jail records show.

Winfield's wife told police detectives that Winfield was killed because he spoke to police about recent shootings in the area and identified Brothers as one of the shooters, according to the warrant.

Brothers was booked with second-degree murder in the Aug. 13, 2010 fatal shooting of 33-year-old David

Mitchell on North Marque Ann Drive, police have said.

Brothers was accused of trying to rob Mitchell last year and then shooting him when he tried to get away, police have said.

Winfield was lying next to his wife asleep in bed at a duplex on Robbie Avenue when he was shot in the head around 3:30 a.m., police have said.

The couple's son, 16, was asleep in another room of their home, police have said.

At least five children were in the house at the time of the shooting.

Winfield's wife told police she was awakened by the sound of a gunshot and saw someone in all black clothing and a hood leaving her bedroom, according to the warrant.

A witness sleeping on the living room couch of the Winfield home saw Brothers as he was leaving and recognized him, the warrant says.

Robbie Avenue is located in the Windsor Place subdivision, about two blocks away from Belaire High School on Tams Drive.
