STOCKTON (KTXL) -- The Stockton Police Department has made an arrest in a four-year-old cold case. Investigators said a 76-year-old man has been arrested for the murder and rape of 84-year-old Hazel Dingman.
Investigators said Alvin Guy is a registered sex offender from a 1991 case out of California involving a minor.
In Susan Trinchero's arms is a picture of her late mother.
"It's just so unbelievable," Susan Trinchero, Dingman's daughter said. She was well-loved, friendly, good-hearted and greatly missed.
"My mother was 84 years old and the sweetest woman in the world," she explained.
After four years of not knowing who killed her, Dingman's family is finally getting some answers.
"This is a joyous, joyous day for the Dingman-Frolicker family," Trinchero exclaimed.

The Stockton Police Department arrested Guy for murder and rape. Officers took the registered sex offender into custody Wednesday in Las Vegas. Chief Eric Jones said Guy lived near Dingman and went to Nevada after the killing.
It was back in July of 2012 when Trinchero found her mother dead. Badly beaten with a cane, bound and sexually assaulted at her home on Downing Avenue in Stockton.
The violence left many, from neighbors to law enforcement ,angry and saddened. After so many years they didn't forget about Dingman, about finding answers. For that, her family is grateful.
"We also want to give our thanks to all those people who worked on this case to make this day happen for us," Trinchero said.
Jones did not say if Dingman and Guy knew each other.
Guy is expected to be in a Nevada courtroom on Monday. We should learn on that day when he will be extradited to California.
