No other hospital staff, patients or others were injured, Sheriff David Clarke said Thursday.
Officers went to the seventh floor of the hospital in the Milwaukee suburb of Wauwatosa after learning the man, who was wanted for being a felon in possession of a gun, was visiting the neonatal unit. Officers approached the man, who was holding a baby, and told him he was under arrest.
"He then fled down the hallway and while fleeing produced a handgun and officers were in pursuit," Clarke said. The sheriff would not say whether the man fired any shots. Officers shot and wounded the man, who was taken to another hospital in the medical complex for treatment, the sheriff said.
The hospital issued a statement saying it had locked down the building because of a report at 11:59 a.m. of an active shooter. The hospital would not respond to further questions or general inquiries about staffing on the neonatal unit.
Irma Blazek, an interpreter, was in the cafe on the first floor of the hospital when she heard a code for an active shooter over the loudspeaker. Blazek said she and 10 to 15 other people hid in a stairwell for over an hour.
"It was just bizarre," Blazek said. "This is the last place you would think something g like this would happen."
Angie Denning said she was with her 3-week-old son, who was being treated on the same floor of the shooting, when hospital staff told her about the situation.
"We were in the bathroom. We actually unplugged my son and went in the bathroom and locked the door," Denning told WTMJ-TV.
