Police say a woman who struck a 5-year old girl and her grandmother with an SUV in Worcester, Massachusetts, was chasing down her ex-boyfriend, ramming his vehicle before the incident.

The grandmother and granddaughter were waiting for a bus outside St. Vincent's Hospital Wednesday, when the SUV jumped the curb and hit them.

They were both originally listed in critical condition; however, police say the girl is now in good condition and will be released within day, while her grandmother remains in critical, but stable, condition as she's treated for multiple broken bones.

Police say 33-year-old Cassandra McAuliffe was chasing her ex-boyfriend, Derek Bonin, and was ramming his vehicle. Bonin contacted police, saying he was being followed, and was on his way to the police station for help.

McAuliffe allegedly hit the man's truck several times before losing control.

"She was just stating out loud that she didn't know whatever the police were asking her and that she just wanted to go home," said witness Sindy Francis. "And he just kept saying, 'Oh my God, I can't believe you did this. I can't believe you actually did this.'"

"I really thought that the kid, the little girl, was dead," Bonin said.

The woman driving the SUV has been arrested and charged with domestic assault and battery, two counts of assault and battery with a dangerous weapon causing serious bodily injury, assault and battery with a dangerous weapon on a child under 14, reckless operation malicious destruction of property.

Her name has not been released because it is a domestic dispute.

The woman is expected to appear in court Thursday.
