Man convicted of stabbing Pomona woman to death, killing her dog, then setting her apartment on fire
An Inglewood man was convicted Monday of murdering a woman he briefly dated, killing her dog, then setting fire to her Pomona apartment.
Chaumon Wayan Tyner, 53, was convicted using scissors to murder Ronnie Sue Wall on March 16, 2019. He was also convicted of cruelty of an animal for killing her Yorkshire terrier, Bentley, and arson of an inhabited structure.
"The defendant's actions in this case were brutal and depraved," Los Angeles County District Attorney George Gascon said.
Tyner and Wall had met through an internet dating site, and they dated for just 28 days, Deputy District Attorney Phil Stirling said. Wall was stabbed 11 times with the scissors, and Tyner ransacked her home after killing her, then started a fire before taking off with her car. The apartment's sprinkler system put out the flames.
Authorities believe the couple argued, and telephone records indicated he stayed in the apartment after the killing, Stirling said. He was arrested nine days later by Pomona police and has been in jail since.
Tyner, who had a prior strike from 2003 for robbery, faces a potential state prison sentence of nearly 70 years to life when he is sentenced on Oct. 27.
