PARMA, Ohio -- A 911 caller told police that a suspect shot at two witnesses who interrupted an armed robbery that escalated into the fatal shooting of a gas station owner.

The woman described the aftermath of the shooting that killed Robert Sposit in a 911 recording released Tuesday by the Parma Police Department.

Logan Sinclair, 21, faces an aggravated murder charge, accused of shooting Sposit. A Parma judge on Wednesday set his bond at $3 million, and his case was bound over to the Cuyahoga County Common Pleas Court.

The 911 caller told police that she heard gunshots when she arrived at Sunoco on Pearl Road shortly after 7:30 p.m. on Saturday. She saw a suspect, later identified as Sinclair, fire shots at two witnesses as he ran out of the gas station.

"I pulled in and there were two gentleman, who are deaf," she said. "They were holding the door and I heard gunshots. This guy was shooting at them [while] running out."

Neither witness was harmed, but Sinclair could face additional charges, police said Wednesday.

The woman then went inside the gas station and discovered Sposit had been shot.

"The gentleman's been shot," she said. "Get an ambulance here. This guy's in bad shape."

One of the other witnesses told the woman that Sposit had died. The woman relayed that information to the dispatcher.

The caller told the police dispatcher that the suspect left the area in a gold Nissan. She also provided the car's license plate number.

An officer spotted the Nissan a short time later outside a house on West 46th Street near Brookpark Road. A SWAT team surrounded the house and persuaded Sinclair to surrender, police said.

Sinclair was taken to MetroHealth, where he underwent surgery. He was released from the hospital on Tuesday evening and taken to the Parma Detention Center.

Investigators also discovered Sinclair had robbed Charlie's Beverage on Ridge Road in Cleveland about 30 minutes before he arrived at Sunoco, police said. No one was harmed during that robbery, they said.

Sposit, 50, of Parma, owned the gas station for years, and friends described him as hardworking, honest and respectful. His wife and three sons declined to speak to reporters after Sinclair's arraignment Wednesday.
