Back in 2004, the bodies of Jason Janek and Kevin Abul-Husn, of Whiting, were found in the back of a pick-up truck. Both men were shot in the head.
Wednesday, the Lake County Sheriff announced that Alfonso and Mark Chavez have been arrested in California, and charged with the crime.
Investigators say a person who wanted to clear their conscious came forward with information leading to the arrests.
"We want the community and family to know that we never gave up -- that we continued -- followed up on every lead as a result of members of the community informing us of what they know," said Sheriff Roy Dominguez, Lake County Sheriff's Department.
Investigators say two other suspects are still at large.
