Officials from the Maricopa County Sheriff's Office say a suicide investigation led authorities to a murder victim in Goodyear.
According to MCSO, on Sunday afternoon deputies received a report of a man found dead in a vehicle near Perryville Road and Hunt Highway.
The driver, identified as 45-year-old William Cahill, was found dead inside the vehicle from an apparent suicide, officials said.
As detectives were investigating, multiple videos were found on Cahill's phone along with a note directing someone to watch the clips.
In the videos, Cahill reportedly said he had shot his girlfriend "Daisy" twice and had placed her body in a well.
Officials said detectives had tried to locate Daisy, who was later identified as 37-year-old Carolyn Dahlgren, but were not successful.
On Tuesday, detectives found a private well in the area of 155th Avenue and Queen Creek Road.
Investigators utilized a private well company to recover Dahlgren's body around 9 p.m.
No further information was immediately available.
