Family doubles reward in search for missing Texas student Caleb Harris
Randy Harris pleads for help in the search for his son as family spokesperson Tony Mathis urges people to check home security cameras for possible footage of Caleb on the night he went missing.
Texas college student Caleb Harris has been missing for a month since he left his off-campus, Corpus Christi apartment in the early morning hours of March 4 to pick up a food delivery order.
Harris, a 21-year-old student at Texas A&M - Corpus Christi, had been in contact with friends and family over Snapchat between about 2 a.m. and 2:45 a.m., just before he left to pick up his Uber Eats order and vanished with his phone. His wallet and keys were left behind, according to his parents.
"That seems to be the only item that we're missing," his father, Randy Harris, told "Fox & Friends" on Wednesday. "We have his keys; we have his truck, locked; the dog's back in the apartment. There's nothing else missing."
Later in the day on March 4, Harris' roommates noticed the 21-year-old's food order placed outside their door, as instructed, but he was nowhere to be found, according to the Corpus Christi Police Department.

"It's 2024, and the odds of somebody disappearing without a trace, without anybody knowing anything, are slim to none. We just feel like the word hasn't got out to enough people, and we do believe somebody knows something," family spokesperson Tony Mathis told "Fox & Friends."
Randy Harris also mentioned that his family spoke with Gabby Petito's father, Joseph Petito.

11 a.m.
Harris' roommates find his Uber Eats order sitting outside the door of their apartment building. They also see his truck parked outside their apartment, as well as his wallet and keys inside the apartment, but they do not see Harris.
"Caleb’s roommates, who described him as a homebody and a creature of habit, immediately became alarmed by Caleb’s absence. After searching for Caleb by themselves for a short time, the roommates called the CCPD to report Harris missing," police wrote.
The initial responding officer checked local hospitals to see if any unidentified people matching Harris' description had been checked in earlier that morning. Authorities also searched in and around his apartment and found no apparent signs of a struggle or a possible vehicular accident in the area.

More investigators responded to the scene and conducted "an intensive and large-scale search of the surrounding area."
Police said Harris' friends and roommates have been very cooperative. They also interviewed the female Uber Eats driver who delivered food outside his apartment. The driver told detectives "that she was driving alone that night and did not see Caleb or anyone else at or near the apartment complex."
