A 10-year-old boy died after being struck by a Pima County Sheriff's Department deputy driving an SUV on Tucson's south side Monday.

The boy was treated by paramedics at the scene at South Campbell Avenue and East Wyoming Street, south of Irvington Road, shortly before 5 p.m., said Capt. Barrett Baker, a Tucson Fire Department spokesman.

The child, whose name has not been released, was taken to University of Arizona Medical Center, Baker said. He died Monday night at the hospital.

At 4:45 p.m., Deputy Jesus Verduzco reported to sheriff's communications that he struck a child who was running across the street and needed medical assistance, said Sgt. Maria Hawke, a Tucson Police Department spokeswoman.

Hawke said Verduzco was driving a marked Tahoe north on Campbell and struck the child at Wyoming.

Tucson police said the boy was with a group of children who had been seen running back and forth across Campbell near Wyoming. At one point, the boy who was hit was on the east side of the road and the rest of the group was on the west side.

The boy ran out across the street to join his friends when he was struck by the deputy's vehicles, Tucson police said in a news release. The deputy swerved in attempt to avoid striking the boy but was not able to avoid the collision, police said.

There was no indication that the deputy was speeding at the time, police said.

Tucson police are heading the traffic investigation because the incident took place within city limits.

The Sheriff's Department will handle the administrative investigation to determine whether the deputy followed proper standards and procedures.

Verduzco has been with the department for five years. He was placed on administrative leave, which is standard procedure following a major incident, the sheriff's department said.
