According to People, police were called to Bruns' Staten Island home on Monday afternoon by a friend who checked in on her, only to find her unconscious in her bedroom.
Local media reports said Burns was found Wednesday near bottles of prescription pills and what may be a suicide note, however, police would not confirm those details.
On March 5, Bruns was behind the wheel of her vehicle when she fatally hit two children in a Brooklyn crosswalk and caused a woman to lose her unborn child.
Tony Award-winning actress Ruthie Ann Miles was crossing a street in the city's Brooklyn Park Slope neighbourhood on 5 March when she and her four-year-old daughter Abigail were knocked down by Bruns.
When the crash occurred in March, Bruns had allegedly been driving her vehicle westbound on 9th street when she allegedly ran a red light and struck a group of pedestrians, including Miles, Lew, and their children.
Abigail was killed and her mother was taken to hospital, where she lost the baby girl she had been expecting with husband Jonathan Blumenstein.
She had been repeatedly warned not to drive by doctors after suffering a previous medical episode.
Bruns faced 15 years in jail after being charged with manslaughter, criminally negligent homicide, reckless endangerment, and assault following the accident in March. Laura Lew and her one-year-old son Joshua (right) were also hit.
Blumenstein, who goes by the stage name Ruthie Ann Miles, won a featured actress Tony in 2015 for her role as Lady Thiang in a revival of Rodgers and Hammerstein's 'The King and I'.
