The widow of an Oregon man who was beaten to death is suing his alleged killer's business tycoon father.

Bradley Cole, 69, died in May of last year outside of Ashley Inn & Suites in Lincoln City after he was assaulted by Roland Evans-Freke, 31, police said.

In a lawsuit, seen by Oregon Live, filed by Cole's wife Debra, Evans-Freke is said to have had a history of being hospitalized inside psychiatric units.

His father, Stephen Evans-Freke, a former Wall Street investment banker worth $25 million, is named as a defendant in the suit.

The suit alleges that the hotel and Evans-Freke's father were both negligent in failing to intervene and prevent his 'worsening violent outbursts'.
