Austin police are looking for Frank Towers, 33, who was reported as a missing person Thursday.

Towers’ sister told police she hasn’t seen or heard from Towers since July 23. She said his cell phone goes straight to voicemail when she calls.

Officers checked Towers’ apartment twice Thursday and he was not there. His bike was also missing.

Towers is Caucasian, 5’7”, 180 pounds and has blonde hair and green eyes. He is possibly without his medication.

If anyone knows of Towers’ potential whereabouts, contact local law enforcement officials immediately.
