The woman whose car hit and killed two young children, including the 4-year-old daughter of Broadway star Ruthie Ann Miles, has been found dead following an apparent suicide.

After not hearing from her for awhile, a friend went to check on Dorothy Bruns, 44. When first responders arrived at her Staten Island hoe, Bruns was found unconscious and unresponsive in a bedroom with no obvious signs of trauma. Emergency medical responders on the scene pronounced her dead.

According to police, Bruns died of an overdose, and she left behind a note “expressing [her] desire to no longer live.”

In March, Bruns was behind the wheel of a vehicle that struck and killed two pedestrians in Brooklyn: Miles’ 4-year-old Abigail Blumenstein and a family friend’s son, 1-year-old  Joshua Lew. Miles was seven months pregnant at the time, and she and Lew’s mother Lauren were hurt in the incident.

Two months later, Miles’ family lawyer Ben Rubinowitz shared the heartbreaking news that  Miles and her husband Jonathan Blumenstein had lost the baby girl they had named Sophia Rosemary Wong Blumenstein.

Earlier in May, a Brooklyn grand jury indicted Bruns on charges of criminally negligent homicide, manslaughter and assault. Police have said that Bruns claimed she had a seizure at the time of the crash, in which she hit parked cars and dragged Lew’s stroller halfway down the street with the baby still inside. Bruns had previously received tickets for running  red lights.
