Many of the 71 people shot were accounted for at hospitals or on scene, but some parents and relatives showed up to the school Friday morning with hopes of reuniting with kids they were unable to reach. Tom Sullivan held up a flyer of his son, Alex, asking reporters if they had seen him, according to the Associated Press. Alex was celebrating his 27th birthday by attending the premiere.

A witness named Caitlin, who said she was in the theater when the shooting happened, went to her twitter account to say her friend Alex was still missing as of 8 a.m., ET.

Byron Settles was also at the school looking for his nephew, Tyrell Hardiman, according to the Associated Press. Settles said it was unusual that Tyrell wasn't at work when he was supposed to be there.

A reporter for the Denver Post tweeted out about the missing nephew, using a different spelling, writing that his uncle was "desperately looking for him."

Suspected shooter James Holmes, 24, is in police custody. Authorities said they believe he was the only gunman.
