Children's Hospital of Wisconsin also gave the following update via Twitter:

UPDATE 2:03 p.m. EST: Milwaukee County Sheriff David Clarke said Milwaukee Police Department officers conducting a warrant pickup shot the suspect, who was wanted on felony possession of a firearm. He wouldnt't discuss whether the suspect was able to fire off any shots.

"No hospital personnel have been injured in this incident," Clarke told a 2 p.m. news conference.

He said authorities received a call around 11:59 a.m. of an active shooter at Children's Hospital of Wisconsin. The officers approached the suspect, who was holding a baby in the neonatal progressive care unit of the hospital, and told him he was under arrest. The suspect then put the baby down and indicated he wanted to cooperate, but instead fled down a hallway.

The suspect then produced a handgun, and officers fired several shots at him, and he is being treated at a local hospital. Clarke said the baby and the baby's mother are "fine."

After Clarke was questioned about the officers' tactics, he responded by commenting on the suspect bringing a gun to a children's hospital.

"What's this idiot doing in a neonatal caree unit with a handgun?" the sheriff asked rhetorically.
