An investigation is underway after a National Guardsman was hit and killed by a driver in the North Natomas area of Sacramento on Wednesday afternoon, police say.

The Sacramento Police Department said the collision happened just after 3:15 p.m. at Del Paso and El Centro roads.

First responders declared the pedestrian dead at the scene. The Sacramento County Coroner's Office has since identified him as 19-year-old Ricky Rey Reyes, Jr.

The driver of the vehicle -- who officers allege was under the influence -- was taken to an area hospital, police said. The extent of the driver's injuries was not known, but the car was left in a small ditch off the side of the road with severe damage.

Ricky Reyes, Sr., received a life-changing knock on his door when officials told him his son had been killed by an alleged drunk driver.

He said his son took pride in his day job at Corti Brothers, an east Sacramento grocery store and deli. His dad said he made one heck of a sandwich and loved meeting new people.

"My son, he was amazing, way better than I was. Beautiful soul, loving, caring, always giving," Reyes, Sr., said.

Alyssa Reyes said her son was her world and her rock. She said she grew up with him as a young mom.

"I miss my son. I want him back," she said. " I know I'm not going to get him back."

The family said Reyes, Jr., put service first, pending his weekends at the National Guard base in Sacramento, preparing for a future in the military.

The circumstances of the collision are under investigation.  

Eastbound Del Paso Road was closed up to El Centro Road due to the crash.
