Federal authorities have new leads in the search for the remains of an Israeli tourist who disappeared in 2003 after he picked up an escaped prisoner who was hitchhiking in Texas.

Jonathan Lee Vernier, 36, was convicted last week Thursday on federal charges of carjacking with intent to cause death or serious bodily harm in the death of Israeli tourist Ran Mesika, 22.

Vernier admitted in testimony this past week to disposing of the body in Louisiana between Lake Charles and Crowley.

Vernier had escaped from a Colorado prison and was hitchhiking along Interstate 10 in Texas when Mesika stopped to give him a ride in April 2003.

Prosecutors said Vernier struck Mesika after traveling a few days with him and then stole his van.

His testimony along with other evidence has lead investigators to search near Welsh off Highways 1126 and 99, along Lyons Road.

Local authorities are assisting Federal agents in the search.
