An 83-year-old Northern California woman has died after being hit by a skateboarder moving at 15 to 20 miles an hour, police said.

Maryann Slettehaugh was crossing a street in Capitola, California, Tuesday afternoon when she was struck by a 17-year-old boy, Capitola police Sgt. Andrew Dally told CNN affiliate KSBW-TV.

Dally said the skateboarder, who was traveling down a steep hill, jumped off the board and tried to avoid colliding with Slettehaugh but was unable to, according to KSBW. He stayed with the injured woman after the collision.

Slettehaugh was in a crosswalk and a panel truck had stopped to let her pass, according to media reports.

Slettehaugh was airlifted to a San Jose hospital, where she was pronounced dead, CNN affiliate KION-TV reported.

The teen has not been charged in the incident, but detectives are investigating, Capitola police Detective Marquis Booth told CNN.

Booth said municipal code prohibits skateboarding the Capitola Village commercial district where the accident occurred and the teen was cited for a violation.

"It just isn't a good mix when we have skateboarders," Booth said. "You can gain some pretty good speed going down that hill."

Dally told KSBW, "It was not a malicious type of act. He seemed like a pretty clean-cut and honest kid."

Slettehaugh's husband of 64 years, George Slettehaugh, told CNN affiliate KTVU-TV his wife had been hit by a skateboard 15 years ago.

"She was leery of them and tried to avoid them," George Slettehaugh said in an interview. "[She] kept watching for them all the time."

Maryann Slettehaugh was on her daily walk from her home to the beach when she was struck, according to media reports.

"It was her daily routine. She lived just two or three blocks away," Dally told KSBW.
