Detectives have made a third arrest in the Lookout Valley triple murders after 22-year-old Skyler Hudson Allen admitted that he was with Derek Morse and a 15-year-old the evening of the slayings at an RV on Kelly's Ferry Road.
Allen was charged Tuesday with three counts of criminal homicide and one count of attempted criminal homicide - the same charges placed earlier against the 19-year-old Morse and the teen.
An affidavit said all three had firearms and discharged them at the scene of the killings. Multiple shell casings of varying types were found at the scene.
It says the three were seen together on several occasions, including on video, before and after the slayings.
The affidavit does not say that Allen admitted to being involved in the shootings.
A witness reported seeing a black vehicle arrive at Allen's residence at 1324 Burgess Road at 8:15 p.m. on April 9. The vehicle was occupied by two males. The witness said the three left Allen's residence about 10 minutes later with all carrying firearms.
Allen got in the back passenger seat of the vehicle.
The killing happened around 9 p.m. on April 9.
The affidavit says the three were in Trenton, Ga., around 9:15 p.m. They went to several places, including the home of the grandmother of the 15-year-old in Trenton.
Allen said he was with Morse and the 15-year-old until Morse dropped him back off at his house that night.
Allen was arrested on Tuesday at 5:45 p.m. He was taken into custody at the Sheriff’s West Annex.
Authorities said, "With the arrest of Allen, the Hamilton County Sheriff’s Office is confident the three primary suspects in the murders and attempted murder have been identified and arrested. This investigation remains open as detectives with the Sheriff’s Office continue to identify others who provided assistance to the primary suspects after the fact."
Allen's prior criminal charges were traffic related.
Those killed as they congregated near an RV on Kelly's Ferry Road were John Lang, 53; Caleb Boozer, 29, and Jon Morris, 24. Michael Callen, 16, was shot.
