PINELLAS PARK, Fla. (AP) — A Floridacouple told authorities that they were sleeping when their adult son stabbed them multiple times.

The Pinellas County Sheriff’s Office reports that Phillip and Nancy Miller are recovering from the wounds they received during Thursday’s attack.

According to a news release, Nancy Miller was able to escape long enough to dial 911 from her cell phone.

Officials say their 34-year-old son possibly also stabbed himself. Jason Alan Miller is in a local hospital and has been arrested on two counts of attempted first-degree murder.

It wasn’t unclear what provoked the alleged attack.

The investigation continues.
