IRVING - Police say two people are dead, including the suspected gunman, after he opened fire at North Lake College in the Las Colinas area of Irving in what's believed to be a murder-suicide.

Irving police have confirmed that three shots were fired on the campus Wednesday just before noon.

The deceased gunman was described as being a white man with a buzz haircut, who was wearing an orange tank top and black jacket. He was armed with a handgun, police say, and hasn't been identified.

The gunman's body was found in a different building from where the victim was shot and killed, according to police. Officials couldn't confirm which building at this time. 

The Dallas County Community College District says North Lake is still under lockdown, but classes for the remainder of the day are canceled. Classes are also canceled for Thursday.

Irving PD said just before 1 p.m. that there was "no continuing threat" at the school, but officers will keep searching to make sure the campus is safe.

When the events originally unfolded, the school tweeted that the school was under lockdown and advised students to go into the nearest classroom and hide.

One student spoke with KHOU sister station WFAA and said she was in the C Building when she heard three gunshots before running out of the school.

Another witness said officers with high-powered rifles were going room to room searching for the suspect.

A student named Mike spoke to WFAA and said he heard people yelling in a hallway, and a man entered the room he was in, turned off the lights, and locked the door. He also heard police officers telling people to get down, and said officers entered the room and had students leave with their hands over their heads.

Some students have taken to social media to talk about the incident:
