Human remains have been found inside a Texas wastewater collection point near missing college student Caleb Harris' apartment.

There is no evidence yet that the remains are connected to the disappearance of Caleb Harris, 21, according to the Corpus Christi Police Department.

CCPD Senior Officer Antonio Contreras said police responded at 3:31 p.m. after a city water employee found human remains in a wastewater collection point in Ennis Joslin, according to KIII-TV.

The medical examiner will need to determine the identity of the victim, the police said.

Harris was last seen by his roommates on March 4.

The group, all of whom are students at Texas A&M, were at their off-campus apartment playing video games when they briefly went to the parking lot to play with a puppy belonging to the girlfriend of one of Harris' friends before returning to the apartment. 

By 2:20 a.m., the last of Harris' roommates had gone to sleep. Harris let them know he was staying up to place an UberEats order.

Twenty minutes later, Harris sent a Snapchat video to his sister, appearing to show him walking the puppy through the apartment parking lot.

He then sent a Snapchat photo of a bridge over a drainage ditch within a few hundred feet of the apartment entrance to a friend in San Antonio at around 3 a.m.

By 11 a.m., Harris' roommates had discovered the unopened order at their doorstep. His pickup truck was still in the parking lot, and his keys and wallet were located in the apartment. 

Police said the roommates became concerned about Harris' whereabouts, noting he was a "homebody and a creature of habit," and reported him missing.

Throughout their investigation, police have said there is no evidence of a struggle or foul play found within the apartment or in the immediate area.
