The Stony Brook University Hospital nurse and Medford resident was found with multiple stab wounds on the night of July 22, 2021 in a wooded area of Holtsville.
On Thursday, Dec. 7, a Suffolk County jury found her ex-boyfriend, 51-year-old Wayne Chambers, guilty of her murder.
According to prosecutors, Chambers picked McIntosh up in her car at around 7:45 p.m. that evening following her nursing shift at the hospital.
The two had previously dated for six years but were broken up at the time.
Nearly 20 minutes later, someone called 911 reporting that Chambers was driving erratically before stopping on Woodland Avenue in Holtsville.
Witnesses saw him outside the car physically assaulting McIntosh and pulling her hair as the woman screamed.
After noticing the witnesses, Chambers got in the car and sped away.
When emergency crews arrived, they found McIntosh suffering from over 25 stab wounds, including to her neck and back.
She was rushed to Stony Brook University Hospital, the same hospital where she worked, and ultimately died from her injuries.
An autopsy showed that the 46-year-old’s heart and lungs had been punctured in the attack.
Chambers was arrested over a week later, on July 30, by Suffolk County Police and the US Marshals Service at a hotel in Newburgh in Orange County.
Investigators later located McIntosh’s vehicle in the Bronx. Red staining found inside and on the exterior was confirmed to be blood from both her and Chambers.
During the trial, Suffolk County Police officers testified that a female acquaintance of Chambers told them that he had come to her home on the night of the murder with a cut on his finger. She also reported seeing a bloody spot on his shirt.
Cell phone location data also placed Chambers near the murder scene.
“The domestic violence murder of Sandra McIntosh was a tragedy that should not have happened,” said Suffolk County DA Raymond Tierney.
“If you or anyone you know is a victim of domestic violence, I urge you to contact the Police Department or the Suffolk County District Attorney’s Office to help us prevent tragedies like this one.”
In court Thursday, jurors found Chambers guilty of second-degree murder. He faces up to 25 years to life in prison.
Records show that he previously served 14 years in prison following convictions for robbery and promoting prison contraband in 1999.
