AURORA, Colo.—Authorities are trying to determine why an autistic child who went missing for several hours Sunday night was wearing a tracking device that didn’t work properly.
The Life Trak device Brandon Wells was wearing told searchers the boy was several miles from his home, but he was found a short distance from his home.
On May 30, police activated the system designed to locate a Life Trak beacon that Kristina Vlassenko was wearing on her wrist, but they were unable to receive a signal. Her body was found the next day in murky water at an Arvada construction site.
Life Trak Systems officials said their own test of the device Kristina wore showed it was working properly but the water where police found the girl’s body blocked the transmission.
