A 39-year-old man was arrested Saturday on suspicion of murder and kidnapping after the discovery of a 20-year-old man’s body that appeared to have been “severely beaten,” Maui police said.

Police identified the victim today as Keenan Blair.

Blair was found on Holomua Road about 12:30 p.m. Saturday. Officers later discovered his vehicle, which had been set on fire, near the old Paia Gym, police said.

Through an investigation, police identified the suspect as William Douglas Allen and issued an alert Saturday afternoon asking for the public’s help in locating him. Police said he should be considered armed and dangerous.

An off-duty Maui police sergeant spotted Allen in a Paia parking lot about 6 p.m. Saturday, and he was arrested for investigation of second-degree murder and kidnapping.

Police said Allen and Blair knew each other.
