PD: Man arrested in Las Vegas in case of ex-girlfriend's murder in Phoenix

PHOENIX - Police say a former boyfriend of a woman murdered in north Phoenix last week has been arrested.

According to Phoenix police Sgt. Steve Martos, the suspect 53-year-old Wade Ridley was arrested in Las Vegas, Nev. by local police early Sunday morning.

Ridley was found driving the victim’s vehicle and was stopped and arrested, Martos said.

He said Ridley admitted to involvement in the homicide and then a robbery which happened shortly after at a Safeway Pharmacy nearby.

When officers responded to a home near Tatum and Dynamite boulevards just before 4 p.m. Thursday, they found 62-year-old Anne Marie Simenson with obvious signs of trauma. She was pronounced dead just after 4 p.m., Martos said.

Ridley is reportedly Simenson's former boyfriend.

Martos said Simenson lived at the home with her current boyfriend, who is not considered a suspect in the homicide. Officers discovered Simenson's vehicle was taken from the home after the incident.

Ridley may have tried killing another former girlfriend in Las Vegas last month.

Las Vegas police told ABC15 investigators they are also looking into whether Ridley may have been involved in an assault on a woman in January.

Martos said investigators have not ruled out the possibility there could have been other victims Ridley may have wanted to target.

"Certainly we think there's that strong possibility from the standpoint of what he had done with Ms. Simenson here and the young lady in Las Vegas and again anyone else who may have wronged him certainly could have been in his path," Martos said.
