SINGAPORE -

The parents of an American software engineer who believe their son was murdered last year in Singapore have withdrawn from the inquest, saying they have no confidence in Singapore's legal process.
    
Shane Truman Todd's body was found in his Singapore apartment by his girlfriend last June 24, and police have said he killed himself. But parents Rick and Mary Todd have said they consider the evidence fake.
    
On Tuesday, an inquest witness withdrew claims that Todd was strangled. The state, meanwhile, introduced a witness who contradicted the parents' claim that their son was killed before June 23.
    
The parents, who live in Montana, said Wednesday they'll no longer participate in the inquest and will return to the U.S.
    
Rick Todd said the family had "lost faith in the process."
