Search for Caleb Harris begins
11:00 a.m. — One of Harris’ roommates discovered the UberEats order outside the front door and Harris’ pickup truck parked in front of the apartment. Harris’ wallet and keys were left behind in his apartment; all that appeared to be missing was his cell phone.
Caleb’s roommates, who described him as a homebody and a creature of habit, called the CCPD to report Harris missing after searching for him for a short time.
This timeline was constructed after thorough interviews with Harris’ friends, family and roommates.
A preliminary search of the apartment complex and the immediate area surrounding it revealed no signs of a struggle or violence, or any indication of a hit-and-run on the nearby roads.
According to a CCPD statement, firearms and fishing gear, including waders, that belonged to Caleb were found in the apartment. A laptop belonging to Caleb was collected and has been turned over to Forensic Computer Examiners within CCPD’s Organized Crime Unit for examination and analysis.
