A man armed with a pistol burst into a home on Progress Street in north Baton Rouge on Saturday, shooting and killing three women and wounding a man in what police were calling an act of domestic violence.

Police issued an arrest warrant Saturday night for Courtney Williams, 21, of 3119 Midway St., in connection with the shootings inside a residence at 1056 Progress St.

The gunman attacked the victims in the living room and a bedroom of the home at 3:19 p.m., said Police Department spokesman Cpl. L’Jean McKneely.

Relatives and friends on the scene identified the three women who were slain as Clarisa Cobbing, 19; Brittany Lee, 18; and Josephine Lathers, 76, who was Lee’s grandmother.

All three women were pronounced dead at the scene, police said.

A fourth victim, Eric Dozier, 20, was taken to a nearby hospital with non-life-threatening injuries, McKneely said.

McKneely confirmed the names relatives and friends on the scene provided to The Advocate were correct.

The living room and porch of the modest frame house on Progress Street was crowded after the shootings with grieving friends and relatives as dozens more neighbors milled outside, kept at bay by barriers made of yellow crime scene police tape.

Lakeisha Sutton, 19, a granddaughter of Lathers and close friend of Cobbing, said Williams was an ex-boyfriend of Cobbing.

She said Williams had been involved in prior domestic incidents with Cobbing, who was staying at Lathers’ home on Progress Street.

Sutton said she had gone with Cobbing last week to file a complaint with police about Williams taking Cobbing’s 2-year-old daughter from a relative’s house.

She said Williams, who is not the child’s father, had been texting and calling Cobbing demanding that she withdraw the police complaint.

About two weeks ago, Sutton said, Williams was seen spreading gasoline outside the home on Progress Street, but “he was run off before he could set it on fire.”

Clarissa Cobbings’ aunt, Jackie Cobbing, separately confirmed both previous incidents.

McKneely late Saturday was not able to confirm whether Clarissa Cobbing had previously filed a complaint against Williams for allegedly kidnapping her daughter or if there was an outstanding warrant for his arrest at the time of the shooting.

McKneely also said no information was immediately available about the alleged arson attempt.

“I know some incidents have occurred that weren’t reported, domestic incidents,” McKneely said.

McKneely said Williams would be booked with three counts of first-degree murder and one count of attempted first-degree murder upon his arrest.

Anyone with information on Williams or his whereabouts is urged to contact the Police Department’s Homicide Division at 389-4869 or Crime Stoppers at 344-STOP.
