As loved ones gather this week to remember Caleb Harris on what would have been his 22nd birthday, family members continue to believe someone may be responsible for the Texas college student's mysterious death.
A medical examiner ruled his manner of death undetermined, citing the body's level of decomposition, according to MySA.com.
"... we fully believe this is a homicide and not an accident," Randy Harris told the outlet in August.
But as a group of former law enforcement agents continue to help the Harris family seek answers in their son's perplexing death, the university will come together on-campus Tuesday night to honor the late Aggie on his birthday, according to KIII-TV.
The public will have the opportunity to leave messages for Caleb's loved ones and counselors will be available.
Caleb vanished March 4, after a night of playing video games with his roommates at their apartment.
Police said his roommates became concerned about Harris' whereabouts, noting he was a "homebody and a creature of habit," and reported him missing the next morning.
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, but family members said they are certain Caleb's death was not accidental.
