The shooting sent about 100 people fleeing in a “very chaotic scene,” Acting Police Chief Mark Simmons said.
Police are trying to determine who — and how many people — opened fire. No suspects were in custody, and no motive was immediately known, Simmons said.
“A number of our young people — babies — that came to just hang out a little while … left running for their lives (Saturday). And that’s just something that we cannot have happen,” Warren told reporters.
Warren said she spoke to the party’s host, who said she “invited a couple friends over, who invited a couple friends over who invited a couple friends over.”
“And it just got out of control. She’s just traumatized,” Warren said.
The two who died were between roughly 18 and 22 years old, Simmons said, without releasing their names.
The 14 wounded are from 17 to 23 years old, and were taken to two hospitals with what are believed to be non-life-threatening injuries, police said.
Police responded to calls of gunshots around 12:25 a.m. and found dozens of people running away, Simmons said.
Police were not aware of the party beforehand, and had not received any calls for disturbance, Simmons said.
“For our community, (which) is right now going through so much, to have to be dealt with this tragedy (Saturday’s shooting), needlessly — for people who decide to act in a violent manner — is unfortunate and shameful,” Simmons said early Saturday.
“We’re going to do everything that we can as a department to bring those people involved to justice,” he said.
Mayor asks for calm and prayers
Counselors — including those from the city’s schools — are going to be available at five Rochester recreation centers Saturday afternoon to support the community in the shooting’s wake, Warren said.
Warren asked the city to “stay calm and allow these folks (police) to do what they need to do to bring” whoever was involved in Saturday’s shooting “to justice.”
She also asked “everyone to obey the (11 p.m.) curfew … and not have these mass gatherings.”
“Please keep our city in your prayers. Keep the families in your prayers, and of course all these neighbors that live here that had to experience this tragic situation who are all hurting and suffering and crying right now,” she said.
