2 dead in apparent murder-suicide at North Lake College in Texas, police say

— -- Two people are dead at a college campus in Irving, Texas, in an apparent murder-suicide, police said.

Within an hour of declaring an active shooter at North Lake College, the Irving Police Department said one victim is dead and the suspected shooter appears to have committed suicide.

Police said they are no longer looking for a suspect as "there appears to be no continuing threat," but responding officers will continue searching to ensure the area is secure.

North Lake College, a two-year public community college located in the Las Colinas area of Irving with more than 10,000 students, remains on lockdown.

Earlier, police told ABC News there "may be injuries" but could not confirm a number.

North Lake College notified its students and faculty of the lockdown on Twitter, urging those not on campus to "stay away for your own safety."

The college also tweeted that police are on the scene.

Stella Flores, a student at North Lake College, told ABC affiliate WFAA that she was waiting to meet with her school adviser in a building on campus when she heard "three really obvious gunshots, really loud" from two floors below.

"Everybody got their stuff. We ran," Flores told WFAA.
