WAUWATOSA - "The last place I would ever expect (it) to happen," said Milwaukee Admirals President Jon Greenberg.
He was one of hundreds of people either visiting or working inside Children's Hospital when police struggled with, then shot a suspect who had a warrant out for his arrest on Thursday inside the facility.
TODAY'S TMJ4 talked with a number of witnesses who were in the hospital or escaped. Some of the witnesses were on the 7th floor when the struggle and shooting happened.
McKenna Regazzi, a patient at the hospital:
"The nurses were acting calm at first, and I asked my dad 'how are they acting calm? This is scary.' We are in the west tower, it happened in the center tower, but still he could have took the stairs or seomthing. So we were all pretty scared."
Deanna Regazzi, McKenna's mother:
"I think it was handled very well, I think to isolate the situation and did the best they could."
Greenberg, who was seeing his niece on the 7th floor:
"I came to deliver her (a) stuffed animal...got here, and I think I was the last one allowed in the hospital. They ushered me into the holding area...guns were drawn. I was like, 'Holy cow, what in the world is going on out here? I found out it was on the 7th floor...(my sister-in-law) was locked in the bathroom...they were safe. There will be no visiting today."
"(My sister-in-law) just heard a lot of noise, a lot of screaming. All of a sudden, she heard a loud bang against the wall. They were yelling at whoever it was to get on the ground."
"I'm glad it didn't affect any of the patients up there."
Deonte Baldwin, who's son is a patient:
"It was crazy."
"The nurse told us, 'Go to the bathroom, lock your doors.' They just left us...the bathrooms don't lock...what if something happened to my son? It's just me and my girl trying to care for him? That's crazy."
"I didn't know what to do. I got kind of nervous. What's going in this guy's head? Are we all going to be safe?"
"It was just unpredictable...we were just spooked."
Angie Benning, whose son is a patient on the 7th floor:
"We were in the bathroom. We unplugged my son and we were in the bathroom, and locked the door."
"He is in handcuffs, but the nurse did say there is blood in the hallway. They're not sure if that was the police officer's blood or the shooter's blood."
Mike Sanfelippo, whose son was getting a checkup at the hospital:
"At the time we were in the lobby, the announcement came over the loudspeaker...the hospital was being put in the lockdown."
"There were about 30 of us corralled in a corner. There was an open door."
"We saw there was a door open and we got out as soon as we could."
About what his son said during the ordeal: " 'Get out of here.' He was real scared, teared up a bit. Being on crutches, he couldn't run too fast."
Mike Marcouiller, whose wife is an employee at the hospital:
"[I was] feeling a little helpless. Normally I've always been able to take care of the family and it's just like I can't get anywhere near the building."
