A joint investigation involving two Louisiana sheriff’s offices and one in Mississippi resulted in the Sunday capture of two suspects in a double homicide, the St. Tammany Sheriff’s Office said Monday.

A Saturday morning 911 call led to the discovery of two bodies inside a Chevy Tahoe on a dead-end road in Abita Springs, Sheriff’s Office spokesman George Bonnett Jr., said in a news release.

The Coroner’s Office reported both men had been shot, Bonnett said.

After identifying the men, deputies determined the killings may have happened in Mississippi, and notified the Hancock County Sheriff’s Office, Bonnett said.

The victims were identified by the Hancock County Sheriff’s Office as Robert Anthony Criswell, 29, and Joshua Adams, 35.

Two suspects, a man and a woman, were located in Luling and the St. Charles Parish Sheriff’s Office assisted in the arrest, Bonnett said. Their names have not been released.

After the suspects were questioned, the case was transferred to the Hancock County Sheriff’s Office, which will run the investigation, Bonnett said.

The suspects remain in St. Charles Parish on outstanding warrants, Bonnett said.

The Hancock County Sheriff’s Office is searching for another suspect, Bonnett said.
