Evan Marshall had been at a mental health facility for several months.
He was in & out of rehab and mental health facilities for several years. While at the SLS facility in Brewster, employees found a drawing or drawings of a dismembered woman. And, in a journal or to-do list he wrote, before leaving on his day pass, was listed "kill somebody."
He didn't care who it was. He did not know Denise Fox.
The Foxes had only recently moved to Glen Cove. EM had an extensive collection of horror *advertiser censored* and severed mannequins in his basement abode at his mom's home.
On the day of the Fox murder EM deliberately ran down a jogger on a running path. He was reportedly involved in another hit & run, some time before when he was staying with his father in Arizona. He moved back and forth from NY to Florida to Arizona and NY. Investigators queried as to whether EM is a serial killer.
