Other dancers at the club told Hancock County sheriff’s investigators that Terry Speaks, 39, and Margaret Sanchez, 28, were recruiting someone to join them off-site for the night Lockhart disappeared.
Her dismembered torso was found in Bay St. Louis last week. She had been stabbed in the chest.
“We believe they were recruiting someone to go off with them and they finally got one,” Glenn Grannan, chief investigator with the Hancock County Sheriff’s Office, told the Gulfport Sun-Herald.
The suspects were arrested on unrelated charges near Loranger and booked into the Tangipahoa Parish jail.
Mug shots taken after their arrest indicate both had dyed their hair -- Speaks red, Sanchez blue -- since they appeared on surveillance tape at the club.
Speaks fled from the car into adjacent woods bur was apprehended. He faces a federal charge of failing to register as a sex offender in Surry County, N.C., a warrant issued in February.
He was convicted of taking indecent liberties with a minor.
