A man wanted for killing his mother and stepfather in Arizona earlier this week was shot and killed by Missouri state troopers on Tuesday.

The Snowflake-Taylor Police Department responded to a welfare check call on Sunday night and found Cynthia Templeton, 53, and Troy Templeton, 62, dead from apparent gunshot wounds, KNXV reported.

Police were called to the scene by Cynthia Templeton’s ex-husband, who was returning two children to the home and found an open door. According to KTVK, Cynthia Templeton’s 21-year-old daughter was found in the home but was not injured.

Investigators identified Cynthia Templeton’s 23-year-old son, Francis Alcantar Chavez, as a person of interest and issued a “stop and hold” order for him and his vehicle.

Chavez was spotted on Tuesday in Concordia, Missouri, where he engaged in a pursuit with police officers but got away. Missouri State Police later located the vehicle and engaged him in another pursuit, but he “eventually ran into a trooper’s vehicle.”

“Troopers gave chase on foot, at which time, Francis, armed with a handgun, shot at one of the troopers, striking him in the bullet-resistant vest,” police said.

Troopers returned fire, hitting and killing Chavez.

Troy and Cynthia Templeton were both members of the civilian law enforcement auxiliary Arizona Rangers, where Cynthia was a lieutenant and Troy was a ranger.
