CLEVELAND HEIGHTS, Ohio (WJW) — A juvenile was shot early Thursday — one of two overnight shootings now under investigation in Cleveland Heights.

Though city officials said the shootings are separate incidents, investigators believe it’s likely they were committed by the same suspect or suspects. The motives are still unclear.

The two shootings happened just days after a mail carrier was robbed and another man was shot before he crashed into a tree.

The first of the latest incidents happened at about 1:30 a.m. on Thursday. A 53-year-old man who had been shot in his right leg flagged down a patrolling officer in the 900 block of Quilliams Road, near the Randolph Road intersection.

He was shot while he was outside his home, according to a statement from a city spokesperson. He said two younger males dressed in all-black clothing shot at him then fled on foot. Police recovered shell casings from the scene.

The man’s injuries were not life-threatening, officials said. First responders transported him to a local hospital for treatment.

Officers also found a pickup truck with a couple of bullet holes in it along Quilliams Road.

Less than an hour later, just before 2:30 a.m., officers heard several more gunshots nearby, and were led to an apartment building in the 2700 block of Noble Road, near the Elmwood Road intersection, about seven blocks away.

There, they found a juvenile who had also been shot in the leg, along with several shell casings on Noble and Elmwood roads.

Investigators learned a 14-year-old boy was walking in the area with another juvenile when they had a confrontation with two other unknown males near a bus stop. As the 14-year-old was walking away, he said he heard gunshots — then he ran.

The juvenile’s injuries did not appear life-threatening. He was also taken to a local hospital for treatment.

Detectives were still on-scene investigating as of 10:30 a.m. Thursday, according to the city spokesperson.

Earlier this week, males wearing Halloween masks robbed a United States Postal Service mail carrier at gunpoint. The Tuesday afternoon incident also happened along Quilliams Road.

Earlier that morning, just before 3 a.m., officers found a 30-year-old man inside a vehicle that had crashed into a tree after he had been shot in the 3500 block of St. Albans Road.

It’s still unclear if those incidents are connected to the recent shootings.
