One of several suspects wanted in connection with a criminal investigation has taken his own life, according to officials.

The incident happened overnight off of  East Rancier Avenue in Killeen, at around 1:30 a.m. In an interview with ‘Crime Stories with Nancy Grace,’ Guillen family attorney, Natalie Kwaham, said the suspect has been identified as Aaron Robinson. He reportedly ran off of the base on foot. Police attempted to make contact with him but he shot himself as the officers approached.

There is currently no confirmed link yet, but the incident happened hours after the U.S. Army Criminal Investigation Unit announced they had found human remains while searching for 20-year-old Fort Hood soldier, Vanessa Guillen.

Miller said the remains were found close to the items.
