The man accused of shooting and killing three women and wounding a man Saturday had previously been convicted of rape and aggravated battery by a Juvenile Court, and had served a juvenile life sentence that ended earlier this year, East Baton Rouge Parish District Attorney Hillar Moore III said.

Courtney Williams, 21, was convicted in 2004 of aggravated battery and in 2005 of forcible rape, Moore said Monday.

Williams received juvenile life sentences for each crime, Moore said.

Juvenile life means youths ages 14 to 17 can be held in juvenile custody until their 21st birthdays.

Williams turned 21 on Jan. 17.

Moore said he could not release any other information about the crimes.

Williams is accused of killing Josephine Lathers, 76, and her granddaughter, Brittany Lee, 18, both of 1056 Progress St., and Clarisa Cobbing, 19, 1520 Utah St.

The women died at the scene of the shooting, the Progress Street home shared by Lathers and Lee.

The gunman attacked the victims in the living room and a bedroom of the home at 3:19 p.m. Saturday, police have said.

Eric Dozier, 20, was wounded and taken to a hospital with nonlife-threatening injuries.

Williams, 21, 3119 Midway St., surrendered to police Sunday and was booked into Parish Prison on three counts of first-degree murder and one count of attempted first-degree murder.

Williams was also booked on one count each of simple kidnapping and attempted aggravated arson stemming from previous incidents involving Cobbing.

Lakeisha Sutton, 19, a granddaughter of Lathers and close friend of Cobbing, said Williams is an ex-boyfriend of Cobbing, who was staying at Lathers’ home on Progress Street.

Sutton said Williams kidnapped Cobbing’s 2-year-old daughter from a birthday party at a relative’s house on Sept. 5.

Williams is not the child’s father, Sutton said.

An arrest warrant filed Sept. 7 for Williams says he took a child from a home on Lorraine Street after her mother, who is not identified in the warrant, dropped her off at a party.

Williams then called the mother several times, saying he was going to kill the child and flee to Texas, the warrant says.

Police were in the process of issuing an Amber Alert when Williams’ brother called to say he recovered the child from Williams.

Williams’ brother, who was not identified in the affidavit, gave the child to police, who returned the child to her mother, the warrant says.

Four days prior to the kidnapping, Williams allegedly poured gasoline on the front porch and along the side of the Progress Street house where the women were slain, according to an affidavit of probable cause.

A witness saw Williams walking along the house Sept. 1 and smelled a strong odor of gasoline, the affidavit says.

Williams then called Cobbing and told her he planned to burn the house, the affidavit says.

Sutton said she and Lee grew up with Williams, and she never thought he would be capable of killing anyone, despite his threats.

“We didn’t take everything seriously,” Sutton said. “Some days he would be jolly, calling us family, and the next he would just click.”

Sutton said a joint funeral will be held for Lathers and Lee at St. James Baptist Church, 1627 N. 44th St., at 2 p.m. Saturday.

Funeral services will be held for Cobbing at 10 a.m. Saturday at Desselle’s Funeral Home, 263 Eddie Robinson Sr. Drive., Sutton said.
