OKLAHOMA CITY -- A homicide has rattled a quiet Norman neighborhood. Police said someone shot and killed 57-year-old Mary Ellyn Benavidez inside her home just before 4 a.m. Thursday.
While police took suspects into custody, authorities are still unsure whether they are actually related to the crime.
Police said they are speaking with several witnesses and possible suspects to figure out who shot Benavidez.
Two of those in custody were involved in a high-speed chase in Oklahoma City two hours after the shooting.
Crime tape surrounded the home in the 1200 block of Stubbeman Ave. near W. Robinson where the 57-year-old woman was shot.
That's just across the street from Rusty Lister.
"God bless, I don't know what to say. There was a death next door to me," Lister said.
He told News Channel 4 he had to break the news that Benavidez was shot in the chest to one of the woman's family members.
"I'm heartbroken over it," Lister said.
Investigators said Benavidez was found near the kitchen along with two other people.
They said those people are cooperating with the investigation and police were able to get a description of a possible suspect's vehicle.
Two hours later, Oklahoma City Police said that same car was used in an armed robbery at 424 SW 51st St, near S. Walker and SW 59th St.
Witnesses to the robbery were able to describe the car involved and that car matched the one linked to the Norman homicide.
When an Oklahoma City officer saw the car, a high-speed chase began.
Police said they took two people into custody; others in the vehicle got away.
Norman Police Capt. Tom Easley said investigators believe those two people were associated with the homicide.
He said whoever is responsible for shooting knew Benavidez.
Neighbors in Norman said Benavidez was a friendly woman from New Mexico and she lived in the home with a son or grandson.
Police said one of her family members works for the Norman Police Department, although not as a police officer.
