Knox County authorities are searching for two suspects who barged into a mobile home Saturday night and opened fire, killing one man. Another man was critically injured after the homeowner returned fire, according to the sheriff's office.

The man who was killed has been identified as 56-year-old Lester Ott. Authorities have not publicly identified the other victim, who remained in critical condition Sunday afternoon.

The shooting was reported just before 8 p.m. Saturday at 2728 Forest Edge Way, inside a West Knoxville mobile home park called Madison Place.

The male gunmen covered their faces with bandannas, making it difficult for authorities to obtain complete descriptions, said Knox County Sheriff's Office spokeswoman Kimberly Glenn.

Detectives were viewing surveillance footage to try to identify the suspects, Glenn said, adding that the motive for the shooting is unclear at this time.
