Dewayne Bazille was playing basketball, a sport he loved, when he was shot dead Monday night just after 7 p.m. inside a public gym at BREC’s Expressway Park, just south of downtown Baton Rouge.

The 27-year-old’s little sister, Janice Bazille, 24, said her brother was an athlete who had been playing at the park on South 11th Street at the time of his slaying.

Baton Rouge police confirmed details of the shooting and arrested Trestan Coats, 22, in the incident.

Coats, of 842 Peach St., was booked into the East Baton Rouge Parish Prison on counts of manslaughter and illegal use of a weapon with a bail set at $85,000.

Janice Bazille said her brother was an honor student who made a living working in factories. She believes he was shot in retaliation for some type of ongoing argument.

“I don’t know what I will do without him,” she said Tuesday inside her family’s house. Dewayne Bazille left behind a three-year-old son, she said. “He was a positive spirit, very uplifting. He was very giving,” she said. Her brother was the type of person to volunteer to coach children’s sports games at the YMCA, she said.

“I feel like life is cold, people are cold. People don’t think about how their actions would affect families,” she said.

A man visiting the site of the shooting Tuesday said he’s been a friend of Dewayne Bazille’s for about 15 years.

“He’s the one who motivated me to go to school,” said Rashad Sabree, 27. “He told me every day to get out of here.”
