BOSTON, July 7, 2017—A Chelsea man with six OUI convictions and a revoked driver’s license was held pending a dangerousness hearing after he allegedly operated a scooter with a blood-alcohol level more than twice the legal limit, then threatened to shoot “random civilians,” Suffolk County District Attorney Daniel F. Conley said.

PETER McISAAC (D.O.B. 7/27/63) was arraigned in Brighton Municipal Court today on charges of operating under the influence as a fourth or subsequent offense; negligent operation of a motor vehicle; operating with a revoked license; malicious destruction of property; and making threats of death, injury, or substantial property damage under Ch. 269, Sect. 14, of the Massachusetts General Laws.

At the request of Assistant District Attorney Margaret Hegarty, Judge Myong J. Joun held him without bail pending a July 14 hearing to determine whether there is “clear and convincing evidence that no conditions of release will reasonably assure the safety of any other person or the community.”  

McIsaac has OUI convictions from Middlesex County in 1985, 1989, 1990, 1991, 1992, and 1993, prosecutors said in court.

State troopers came across McIsaac’s red 2017 Agility scooter stopped along Nonantum Road at about 10:20 last night. Its lights were off and two men were standing nearby. When troopers approached, the men walked away in different directions.

The first man told troopers that McIsaac had picked him up on the scooter earlier, and that they had stopped at a liquor store before hanging out together. They were on their way back to McIsaac’s home when the scooter ran out of gas just moments before the troopers arrived.

As troopers spoke to this man, McIsaac allegedly staggered toward them and stated that he owned the scooter. The troopers immediately noted his slurred speech and detected the strong odor of alcohol as he spoke.

“I’m very intoxicated,” he allegedly added.

Troopers ran McIsaac’s license status and learned that it had been revoked. Based on McIsaac’s unsteadiness on his feet, troopers determined that field sobriety tests could result in him falling and injuring himself. Having formed an opinion that McIsaac was intoxicated and had moments earlier been operating the scooter, troopers took him into custody.

On arrival at the Brighton barracks, McIsaac fell out of the cruiser and required assistance to stand. He allegedly consented to a breath test, which revealed a BAC of .185, prosecutors said in court.

Following the breath test, McIsaac allegedly became very angry and began threatening troopers, their families, and others. He allegedly stated that he had access to firearms and would “kill 15 people,” including uniformed officers, “random civilians,” and children, because he “was wronged.” McIsaac allegedly urinated throughout his holding cell, requiring the response of a HAZMAT-certified cleaning company.

McIsaac was represented today by attorney Jessica Gallagher.
