According to officials at a news conference, it appears three people were injured - but the account of who they were differs from information we received earlier from a school spokesman.
One person – a school maintenance worker – was accidentally shot during an altercation between two other people, Harris County sheriff's Maj. Armando Tello said. That man was shot in the leg, is in his mid-50s, and is in stable condition, said Richard Carpenter, chancellor for the Lone Star College system.
The two people suspected of fighting each other also were injured, Tello said. Tello did not say how they were injured.
Tello also said one handgun was involved in the incident. When asked whether only one person was armed, Tello said he didn't know. Earlier, a school spokesman had said two gunmen were involved in the incident.
Also, a fourth person – a female who has a student ID – was taken to a hospital with some sort of medical condition, Tello said. Earlier, a federal law enforcement source told CNN that someone had suffered a heart attack.

An unidentified Lone Star College student who says she witnessed some of the shooting told CNN affiliate KHOU that an argument between two people preceded the gunfire.
A gunman, she said, told someone: "I don't want to fight you; I'm not trying to go to jail."
The witness appeared to reference only one gunman; it wasn't clear whether she saw a second gunman. She said he "actually turned away from the situation" at first but eventually pulled a gun out of a backpack. She said she heard about nine shots.
"I think it was a bunch of crap that could've been resolved and never should have gone that far," the witness said.
