PROVIDENCE, R.I. (WPRI) — An investigation is underway after three men were shot in Providence Thursday night, according to police.

The shooting happened on June Street just before 8 p.m.

All three men, who are believed to be in their 20s, were rushed to the hospital. Police said at least two of the victims are in critical condition.

Detectives were seen focusing their attention on a nearby picnic table, where a backpack and shoes were left behind. One parked vehicle also had its window shattered and a black SUV was towed away.

“We think it might have been somebody who got out of a car and started shooting. It could be back-and-forth shooting, we don’t know yet. That’s how early it is [in the investigation],” Providence Police Maj. David Lapatin said. “Whatever it is, we know it’s done right now.”

It’s unclear whether police have anyone in custody.
