A Texas A&M University student who was last seen near the main campus has been missing for four days, officials said.
Tanner Hoang, 22, was last seen around 11 a.m. Friday at The Trails at Wolf Pen apartment complex in College Station, the eastern Texas city that is home to the university's main campus, according to a poster published by the Amber Alert Network Brazos Valley.
Hoang was seen possibly driving a silver 2009 Lexus, according to the poster. His family reported seeing video of his vehicle driving west on Highway 21, as if leaving the city of Caldwell.
College Station police are investigating with the help of the Texas Department of Public Safety, police spokesperson David Simmons said.
"There are no further updates at this time," Simmons told NBC News. "We ask the public to contact us if they have any information as to his whereabouts."
Texas A&M University did not immediately respond to requests for comment.
