HARRIS COUNTY, Tx (BELO AFFILIATE) -- Three people were shot at Lone Star College in Texas Tuesday during an argument between a student and another man.
Those two men both ended up with gunshot wounds, and one of them shot and wounded a maintenance man who was an innocent bystander, according to acting Harris County Sheriff Armando Tello.
The shooting led to a campus lockdown and two-hour search for the gunman who got away. Several nearby Aldine ISD schools were also put on lockdown as a precaution.

A law enforcement source said the gunman shot the man he was arguing with, then accidentally shot himself in the buttocks.
Lone Star College student Brittany Mobley said she saw the whole thing happen.
"I saw two dudes basically get into an altercation and the dude that shot, he basically got angry and started shooting the other guy," Mobley said. "A lot of people heard a lot of shots."
Mobley said the suspect had the gun hidden in his clothes.
"Basically, I seen the dude that shot him and as soon as I heard the bullets flying and the gun being fired off, then everyone started running and it was a hint for me to start running as well," Mobley said.
The shooting happened in the central courtyard of the campus in the 2700 block of W.W. Thorne Drive in north Harris County.
Mark Zaragosa, an EMT student, got some hands-on experience when he spotted two wounded men before police arrived.
"I actually had just come out of EMT class and I noticed that there were two downed victims so I stopped to render assistance," Zaragosa said.
The man involved in the argument was shot three times and is reportedly in critical condition at Ben Taub Hospital.
The maintenance man was shot in the leg and is expected to be OK. He was also taken to Ben Taub.
A student on the campus was taken to the hospital after suffering a possible heart attack.
The campus and nearby Aldine ISD schools were put on lockdown while dozens of law officers searched each building for the second suspect. They also searched a nearby wooded area and the neighborhoods surrounding the campus.
Around 2:15 p.m., the suspected gunman turned himself in at Northwest Medical Center with a gunshot wound, according to law enforcement sources.
Lone Star College closed for the rest of day, but students and faculty were allowed to return to pick up their cars and other belongings.
