JENNINGS — People living near a husband and wife found dead in their home over the weekend described Katrenna and Charles Williams as quiet and unassuming.

The couple kept to themselves, bothered no one in the year or so they lived in the small home on Seagraves Street, and watched their son, now 4, play outside on his toy four-wheeler, neighbors said Tuesday.

“His daddy’d sit on the porch and the little boy would ride and ride,” said Mike Benoit, who works nearby at Acadiana Rentals.

Jennings Police Chief Todd D’Albor said Tuesday that investigators now are “looking at all avenues,” and that he wouldn’t comment on the Williamses’ prior problems with law enforcement authorities.

“I don’t want to speculate on anyone’s past dealings,” he said.

The Williamses had been awaiting trial on cocaine distribution charges, according to records in Jefferson Davis Parish’s 31st Judicial District Court.

Katrenna and Charles Williams were arrested in July 2011 and booked on counts of cocaine distribution and child endangerment.

D’Albor said detectives are “methodically” going through evidence, and that as of Tuesday afternoon, 10 people had called in with viable tips.

Police have not released a cause of death.

On Sunday before 5 p.m., a family member found the bodies of Katrenna Segura Williams, 30, and Charles Williams Jr., 25, in separate rooms, D’Albor said.

Their son was found in the home unharmed, the police chief said.

D’Albor said police continue to investigate the slayings that detectives believe was carried out by more than one person late Friday or early Saturday.

D’Albor said he expects autopsy results soon.

On Tuesday afternoon, the Williamses’ white Ford F-150 and gray Pontiac G6 sat parked outside the small home with aluminum siding and cement blocks, nestled on quiet Seagraves Street, less than 1,000 feet from a railroad track.

Near the front door were a boy’s toy all-terrain vehicle, T-ball bat and ball.

One next-door-neighbor, William Earl, said he heard a “boom” Friday night, though “it didn’t sound like a gunshot.”

Across the street from the couple, Yvonne Murray said she heard someone in her driveway Friday night.

Murray, who has a handicap-accessible ramp outside her mobile home, didn’t get up to see what the noise — possibly from a vehicle — was.

She said police did not question her.

“I was surprised,” Murray said. “I thought they would have … I’m a night owl.”

Court records show the Williamses were arrested in July 2011 after a tip from an informant led police to the couple’s Jennings apartment.

Among the evidence seized were more than 28 grams of cocaine, Jaguar and Ford vehicles, and $26,305 in cash, records show.

Records also show the couple’s trial date was repeatedly postponed: Jan. 23, 2012; Oct. 3, 2012; Oct. 16, 2012; Nov. 26, 2012; Jan. 28, 2013.

The next court date was to be a hearing on a motion to suppress evidence, slated for March 14, records show.

Chief D’Albor said the Calcasieu Parish Forensics Unit and the Calcasieu Crime Lab are assisting the investigation. He said he believes his detectives will solve the case.

D’Albor said the Jennings police tip line is answered 24 hours a day, seven days a week, and that an investigator answers the phone. He said anyone with information can call the line at (337) 275-9002.

“We’re being methodical,” D’Albor said. “We believe that by being thorough we can solve it. We want to give these families closure.”

The victims’ son, whose name has not been released, was medically examined and is now with family members, D’Albor said.

The Williamses’ neighbors said they were grateful someone survived.

“At least they had the decency to leave him alive,” Benoit said.
