Scottsdale Detective Ryan So died in a gun accident, authorities say

Scottsdale Detective Ryan So died after a gun accident while unloading a police vehicle, according to a preliminary report from investigators.

So, a member of the Scottsdale Department’s Special Assignment Unit, along with other detectives, had executed a search warrant and arrest and was unloading equipment. As he was removing a bag from the vehicle, a gun fell from the bag onto the ground. When it hit the sidewalk, the gun fired, hitting the victim, investigators found.

Detectives rendered aid, but So died from his injuries after being taken to a hospital.

The report on So’s death came from the Mesa Police Department as part of the East Valley Critical Incident Response Team partnership. The information was released late Friday evening.

“The loss of Detective So is deeply felt by the entire community,” Scottsdale police said in a statement. We will forever honor his sacrifice and remember his legacy as a hero who dedicated his life to serving and protecting others.”

The department declined interviews at this time.

So he was a nine-year veteran of the force and had served four years in the U.S. Navy.

Officials said the crash happened near 76th Street and Greenway Hayden Loop on Thursday around 7:30 p.m. Officers escorted his body to the Maricopa County Medical Examiner’s Office.

“This is an unimaginable tragedy for both Ryan’s family and his law enforcement family at SPD. Our thoughts and prayers are with Detective So’s family, his team and everyone within our police department,” Scottsdale officials said in an update on social media.

So was survived by his wife and three children.

A newly formed regional task force is now investigating cases of use of force and officer-involved shootings in the East Valley. The Mesa Police Department was assigned to conduct the investigation into So’s death.
