A Youngstown woman, who was attacked as her daughter was being murdered, is suing the ambulance company and the EMTs that responded to the crime scene.

A judge in Mahoning County is hearing a lawsuit claiming negligence on the part of AMR ambulance.

The suit, filed by Denise Johnson, alleges that the EMTs who arrived at the home of her daughter, Erika Huff, drove away after the man who was eventually convicted of killing Huff told an ambulance crew that no one had called them.

Lance Hundley has been sentenced to death for murdering Huff at her Cleveland Street home in Youngstown.

Investigators say Huff, who suffered from MS and was wheelchair-bound, pushed her medical alert button on the night of her murder, November 6, 2015.

Police later learned that Huff had been beaten to death before her home was set on fire to cover the crime.

Investigators say Hundley also attacked Huff's mother, Denise Johnson, with a claw hammer outside of the home.

The lawsuit says that the hammer broke off on her head. Hundley had a knife to her throat, and he attempted to kill her by burning the house down, but she still managed to survive.

According to the suit, Deanna Ailes and Brittney Koch, EMTs with Rural Metro, which is part of AMR, "Were met at the front door by a man with a black hoodie who advised that no person had made an emergency call from that house and that no emergency existed at that house."

An unidentified dispatcher is accused of failing to instruct EMTs to perform a patient assessment and failing to advise them of Huff's medical needs.

The lawsuit seeks $150 million in damages and alleges wrongful death of Erika Huff, personal injuries suffered by Denise Johnson, negligent hiring/training/supervision of defendant AMR, and loss of consortium of Lonnie Johnson.
