The Hamilton County Sheriff's Office has arrested another juvenile in connection with the April 9 Lookout Valley triple homicide.
This makes the fourth arrest in connection with the first triple murder the county has seen since 1988.
The unnamed juvenile was arrested about 4:50 p.m. Thursday on a charge of accessory after the fact and was taken to the Hamilton County Juvenile Detention Center, according to a news release. No information was given on the juvenile's age or gender.
Three other people -- Derek Madison Morse, Skyler Hudson Allen and an unnamed 15-year-old boy -- have been arrested on murder charges in the shooting that left Jon Morris, 24; Caleb Boozer, 29; and John Lang, 53, dead, and injured 16-year-old Michael Callen.
Law enforcement officials haven't said anything about why the shooting happened but said it was not a random act.
When Allen was arrested this week, Sheriff Jim Hammond said investigators would keep working to identify those who had provided assistance to the suspects after the killings.
The investigation remains active.
