Police said a blue sedan being driven by 28-year-old Brian K. Green, of Waterbury, crossed the yellow line and hit a silver sedan almost head on. The silver sedan was driven by 59-year-old Mary Gabriele, of Terryville.
Both Gabriele and Green died from injuries suffered in the crash, police said.
On Thursday afternoon, police said Green had cocaine on him at the time of the crash.
Police said the impact of the collision "was severe and caused both vehicles to rotate about their axis." The vehicles were towed from the scene to police headquarters.
Thomaston Avenue was closed to traffic for several hours for the police investigation.
"There have been a fare amount of accidents on this road in the past. This is a tragic situation. We don't really respond to many accidents on this part of the roadway," said Waterbury Deputy Police Chief Fred Spagnolo.
