[Updated at 4:30 p.m. ET] Both suspects are now in custody, CNN affiliates KHOU and KTRK reported. CNN has not yet independently confirmed this information.

Authorities are expected to conduct a news conference at about 5 p.m. ET.

[Updated at 4:03 p.m. ET] Police believe the second suspect fled into woods nearby, a law enforcement source briefed by officers on the scene told CNN.

Authorities are focusing their search on the wooded area, which is adjacent to George Bush Intercontinental Airport, the source said.

[Updated at 3:59 p.m. ET] 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.

[Updated at 3:23 p.m. ET] Texas Gov. Rick Perry is being briefed about the situation by law enforcement personnel, Perry spokesman Josh Havens said.

“(Perry’s) thoughts and prayers are with those that have been impacted,” Havens said. “We have nothing more to add at this point, but the governor will continue to closely monitor the situation.”

[Updated at 3:17 p.m. ET] A freshman who was in a nearby classroom, Amanda Vasquez, tells CNN’s Brooke Baldwin that she heard about six shots. She says she heard from other people that some shooting happened in a library, but she believes that the gunshots she heard came not from the library, but from the hallway outside her class.

“I was in the academic building, waiting for English class to start. I heard about six shots, and kids started rushing down the hallway. A few came into our class. It really happened so fast,” she said.

She said people were shouting, and she hid under a table in a corner of the classroom. She called her mother.

“I called my mom to (let her know) I was OK (and that) I loved her, just in case anything was going to happen,” Vasquez said. “… At first she didn’t believe me … but I kept telling her it’s happening and need you to call the cops.”

[Updated at 3:06 p.m. ET] Someone – a fourth person – suffered a heart attack, according to a federal law enforcement source who is receiving reports from the scene, CNN’s Carol Cratty reports.

[Updated at 2:43 p.m. ET] Three people – one suspected shooter and two people caught in a “crossfire” – were wounded in a shooting that appears to have been between two people at the Lone Star College campus in Houston, school spokesman Jed Young said.
