Police were searching for two men who carjacked an SUV and plowed into a group of children and adults selling fruit to raise money for their church, killing three kids and critically injuring their mother and the carjacking victim.
The men carjacked a real estate agent at gunpoint Friday morning, forcing her into the backseat of her Toyota 4Runner.
The SUV sped out of control about a mile from where the carjacking occurred, slamming into the children and adults manning the fruit stand, Philadelphia police said.
Employees at Education Works, an educational nonprofit across the street from the wreck, told The Philadelphia Inquirer they ran to try to help the victims.
A psychiatric patient who killed his caseworker — and grazed his psychiatrist before the doctor pulled out his own weapon and fired back — has a lengthy history of gun arrests, violence and mental health problems, authorities said.
Plotts by then had shot the caseworker in the face and fired several shots at Silverman, including one that grazed his temple and another that struck his thumb, he said.
Police in Upper Darby, where Plotts lived, were aware of at least three mental health commitments — including once after he cut his wrists and once when he threatened suicide — but said such stays can last just one to three days.
Whelan said Plotts had spent time in a mental health facility, but he did not discuss any potential diagnosis.
Plotts also had at least four gun arrests, along with assault and drug charges, according to police and court records.
Hospital policy bars anyone except on-duty law enforcement officers from carrying weapons on campus, said a Mercy Health System spokeswoman.
