3 people die in crashes in Brentwood, East Moriches, Port Jefferson Station, police say

Three people were killed in separate crashes across Suffolk County this weekend, continuing what has been a deadly month on Long Island roads.

At least 21 individuals have died in crashes in Suffolk and Nassau counties in the first 20 days of August, local police departments have reported.

On Saturday, Olivia Montgomery, 20, of Farmingville, was entering westbound Sunrise Highway in East Moriches at 10:50 p.m. when she lost control of her 2016 Dodge Ram, left the roadway and was ejected from the overturned vehicle, Suffolk police said.

Montgomery was pronounced dead at the scene by a physician assistant with the Suffolk County Medical Examiner’s Office, according to police.

Seventh Squad detectives are asking anyone with information about the crash to call 631-852-8752.

The fatal crash was the second on a Suffolk roadway Saturday after a Bay Shore man was killed when his motorcycle collided head on with an SUV on Spur Drive North in Brentwood.

Gabriel Reyes, 50, was westbound just west of Route 111 on his 2018 Kawasaki when he crossed over a double yellow line and struck a 2011 Ford Explorer at 11:40 a.m.

Reyes was transported to South Shore University Hospital in Bay Shore, where he was pronounced dead, police said.

The driver of the Ford, Edwin Espinoza, 38, of East Rockaway, was not injured, according to police.

Third Squad detectives are seeking information about the crash at 631-854-8352.

A driver also died in a single-vehicle crash overnight in Port Jefferson Station, Suffolk police said.

Christopher W. McGuckin, 54, of Shoreham, was driving a 2012 Hyundai Genesis south on Route 112 near Washington Avenue about 12:45 a.m. Sunday when the vehicle struck a telephone pole and a fire hydrant before crashing into a tree, police said.

McGuckin was pronounced dead at the scene, police said.

A photo from the crash site showed the vehicle ripped in half on the side of the roadway.

Sixth Squad detectives are asking anyone with information about the crash to call 631-854-8652.

From 2020 through 2022, Long Island has averaged 18.2 roadway fatalities per month, according to the most recent data available from the Institute for Traffic Safety Management and Research. The total number of fatalities on Long Island roads increased each year from 2019 to 2022, the agency reported.

There has been more than one auto-related fatality reported in Nassau and Suffolk counties on at least three days this month.
