A bicyclist from Milford was killed on Saturday after he was hit by a car in Wallingford.
Wallingford Police said the driver, 35-year-old Derek Fries, had heroin on him and was under the influence.
The Meriden man faces a handful of charges including manslaughter with a motor vehicle, driving under the influence of a drug or alcohol, and illegal possession of heroin.
This as the family of 37-year-old Donald Carelli of Milford is mourning the loss of their loved one.
Authorities said Fries drove his car over the double yellow center line on South Turnpike Road, hitting one of two bikers near the intersection of Toelles Road near the North Haven town line.
Carrelli was thrown off his bike, went over a guardrail, and into the woods. He died at a hospital, police added.
Fries has been released from custody after posting a $25,000 surety bond. He's due in court in June, according to officers.
Police said the bicyclists were riding on the right hand shoulder within the fog line.
Anyone who may have witnessed the crash is urged to give Wallingford Police a call.
