Deputies arrested the 16-year-old after finding Lisa Swanson, 54, unresponsive inside a Parker Strip residence late Saturday.
PARKER, Ariz. — A 16-year-old boy is in custody after his mother was found dead inside their western Arizona home following a reported domestic disturbance, according to the La Paz County Sheriff’s Office.
Deputies were called to a home in the Parker Strip area at about 11:50 p.m. Saturday after receiving a report of a fight involving a mother and son. Inside the residence, they found 54-year-old Lisa Swanson unresponsive. Deputies attempted to revive her, but she was pronounced dead at the scene, authorities said. Officials have not publicly released her cause or manner of death.
The teenage boy had left the home before deputies arrived, according to the sheriff’s office. Investigators later found a vehicle connected to him at a nearby residential complex and located the teen. Authorities said he was taken into custody without incident. Because he is 16 and the case is proceeding through the juvenile justice system, news organizations have not identified him.
The sheriff’s office has described the incident as a domestic disturbance but has not released a detailed account of what happened inside the home before Swanson was found. Authorities also have not publicly announced a specific criminal charge against the teenager or disclosed what evidence led investigators to take him into custody. The case has been referred to the La Paz County Attorney’s Office for further proceedings.
Swanson’s family remembered her as a hardworking mother and a devoted sister. Her sister, Monica Vasquez, told Arizona’s Family that Swanson was known for helping others and working hard. “She was a hard worker. She’s a giver and a hard worker, and everybody knows that,” Vasquez said.
Her brother, Kyle Vasquez, also spoke about the family’s grief following Swanson’s death. “It hurts so much,” he told the television station. Family members said they learned of the death from Swanson’s daughter. The family has not publicly detailed what may have led to the reported confrontation between Swanson and her teenage son.
The case remains under investigation by the La Paz County Sheriff’s Office. Officials have not announced whether prosecutors will seek additional action in juvenile court or whether the teenager could face proceedings outside the juvenile system. No public court ruling establishing responsibility for Swanson’s death has been reported.
Authorities have released few additional details as investigators continue gathering evidence. The teenager remained in custody as the case moved to the county attorney’s office, while Swanson’s family mourned her death and awaited further information about the investigation.
