A man charged in a string of shootings near Atlanta that left three people dead, including a Department of Homeland Security employee who was walking her dog, died in jail Tuesday night, authorities said.

Olaolukitan Adon Abel, 26, was found unresponsive in his cell, according to a statement from the DeKalb County Sheriff's Office. Officials provided medical treatment to the U.S. Navy veteran, but he was later pronounced dead.

The official cause of death has not been determined, but officials don’t suspect foul play. They are conducting an internal review.

Adon Abel was accused of killing Prianna Weathers, 31, and Homeland Security auditor Lauren Bullis, 40, in last week’s attack. Authorities also had been seeking an additional murder charge for Tony Mathews, 49, who was injured in the attack and died Sunday.

Authorities haven't offered a potential motive for the shootings. It’s unclear if Adon Abel knew any of the victims. Police said they believe at least one was targeted at random.
