Volunteers with Texas Equusearch scoured the area around I-10 and Fry Road in search of a man missing since Tuesday.
Trung Ngo, 23, hasn't been seen or heard from since then, according to authorities. Investigators said he was last seen driving a gray 2004 G36 Infinity sedan with Texas license plate number BP2 L036.
Volunteers met up at Second Baptist Church in the 19400 block of the Katy Freeway around 8:30 a.m. Saturday to search for any sign of Ngo.
Ngo has several distinguishing tattoos, including one on his arm that reads "Ngo." Another tattoo on his chest shows a fish on one side and three men wearing helmets and carrying rifles on the other.
If you have any information, you're asked to give police a call.
