KELSO, Wash. -- A teenager was arrested Wednesday on suspicion he stabbed a woman during a botched robbery.

Surveillance video captured 18-year-old Dennis Anderson approaching the woman at about 8 p.m. Friday outside a Kelso motel located in the 500 block of Three Rivers Drive. He got into a fight with the woman, police said, and stabbed her in the chest.

The victim managed to walk to the nearby Guesthouse Inn for help and was taken to a hospital.

As part of the investigation, police said they enhanced the surveillance video and a patrol officer recognized the suspect.

On Wednesday, the victim also identified Anderson from her hospital bed and police went to a south Kelso house to arrest him at about 3 p.m.

The suspect was cooperating, Kelso police said, until a detective tried to take him into custody. Anderson attempted to run past a police captain who was blocking the doorway. Officers said the two fought for several minutes.

Officers said the suspect was taken into custody and later confessed to attempted robbery and first-degree assault. Anderson's bail is set at $350,000.

Kelso police have not identified the victim, who is still hospitalized for her injuries
