A 69-year-old Scranton man threatened to kill two men with a knife during an argument over fireworks on the Fourth of July, city police said.

Patrolman Anthony Roberto responded to 315 New St. on Saturday around 7 p.m. for a report of a large fight between several people.

Upon arrival, other officers had defused the situation so Roberto spoke with the two victims, Ronald Gibbs and John Dimaur, according to a criminal complaint.

Gibbs said he heard a loud verbal argument between several people outside his home at 315 New St. and witnessed several people in the road, including Dimaur, police said.

Gibbs then saw an unknown suspect approach Dimaur and start yelling erratically at him, according to the criminal complaint.

When Gibbs attempted to separate the men, the unknown subject struck him in the face several times, causing a bloody nose and bruising, police said.

Then, Walter Brown showed up and told Gibbs he was going to “kill him” and to “stop fighting or you’re going to get hurt” while brandishing a 9-inch kitchen knife, according to the criminal complaint.

Dimaur told police that he and a friend — identified as Glenn Marr — had gone shopping for fireworks in the morning and placed them on the porch at 312 New St. until Dimaur retrieved them around 6:10 p.m., officers said.

As Dimaur arrived, Brown exited the residence and a verbal argument ensued over who purchased the fireworks. Brown went back inside, returned with the knife and threatened to stab Dimaur if he didn’t leave the porch, police added.

Dimaur said he had a receipt for the fireworks, and Marr also told officers that he and Dimaur bought them, according to the criminal complaint.

Brown claimed he never showed a knife and the argument was only verbal, police said. Brown also said he didn’t know the person who had struck Gibbs, and that he was cooking on the grill while the incident was occurring.

Police took Brown into custody and found a large kitchen knife inside his residence, determined to be the one used in the incident, according to the criminal complaint.

Police charged Brown, 312 New St., Room 22, with terroristic threats, simple assault and disorderly conduct.

As of Monday, Brown remained in Lackawanna County Prison in lieu of $50,000 bail. A preliminary hearing is scheduled for July 15 at 10:30 a.m.
