Many questions remain following a shooting that left one man dead and one wounded on Waterbury Avenue on Friday night. What's known is that a party was taking place at the second-floor residence when the gunfire rang out after 9 p.m., said Mayor Michael Summers.

Neighbors reported hearing at least three shots. The first victim was shot and killed inside of 2051 Waterbury Ave., while the second man was shot in the leg in the driveway of the duplex, just south of Madison Avenue.

He was taken to Fairview General Hospital in Cleveland, and his condition is unknown, Chief Tim Malley said. Police have "several" suspects in custody, but it's not yet clear if other suspects are still at large, said Summers, adding that there are a number of eyewitnesses.

"Why this happened is yet to be determined," he said. "This is not a random event, it's one of those situations that just went out of control in an unknown and violent way."

Police have not yet released any additional details about the shooting.

"We really don't know much at this time," Malley said. As of around 10 p.m. on Friday night, a Rocky River police officer posted at the described one suspect on the loose as a 220-pound black man with tattoos on his face and neck, wearing a gray sweatshirt with a stick figure design on it.
