5 years later, no arrests in murder of Kenner couple found floating in Lake Pontchartrain

The bodies were found July 9, 2010. Relatives had hoped investigators with the St. Tammany Parish Sheriff's Office would make a quick arrest in the 2010 murders, but justice has been elusive.

"In the first year and a half, they kept coming to us, keeping us on top of everything," Berry said. "After not hearing from them in a year or so, it got tough. I expected it to be solved, I really did."

Glass's brother, Charlie, 63, said the murders consumed his every thought. "Early on, I was obsessed with it. But his pastor and mine said I needed let it go and let the police handle it," he said.

St. Tammany Sheriff's Office detectives have a person of interest in the case, but aren't prepared to call anyone a suspect, according to Capt. George Bonnett, spokesman for the department. "It is an active and open investigation. Our detectives are working leads as they develop," he said.

Kenner couple found in Lake Pontchartrain had just inherited some money - July 15, 2010

A newlywed Kenner couple whose bodies were found in Lake Pontchartrain Friday after an execution-style shooting had recently come into an inheritance, a bit of news they had not been shy about spreading, authorities said Wednesday.

Investigators also discovered that the Toyota Camry owned by the victims, Herbert Glass and Lynette Williams, was found ablaze at an Interstate 59 exit near Pearl River a day before their bodies were recovered from the lake, though so far there is no indication that the slaying took place at that site.

The revelations shed a small glimmer of light on a puzzling case. Investigators are still uncertain about where the couple was killed, what the couple had been doing in the time leading up to the slayings or whether the money was indeed the motive for their murder.
