PHILADELPHIA (AP) - Jail officials in Philadelphia are investigating the fentanyl overdoses of four inmates last week, three of whom died.
Officials said Wednesday that three of the men arrived at Curran-Fromhold Correctional Facility on drug charges Friday. They were unresponsive during routine checks the next day.
Two of the men died, and one was hospitalized.
A fourth prisoner who was hospitalized after an overdose last weekend died Wednesday.
Tests showed all four cases involved fentanyl.
A city spokeswoman says the jails department is investigating whether the drugs were obtained in the prison and whether the four cases were related.
