SAN DIEGO -- A pedicab driver involved in a fatal accident on Saturday may face vehicular manslaughter charges, 10News reported.

San Diego police said Sucru Safacinar, who is from Turkey, was driving his pedicab unsafely when 60-year-old Sharon Miller was thrown from the pedicab, hit her head on the sidewalk and was later declared brain dead at the University of California, San Diego Medical Center.

"I am so sad, about this," said San Diego city councilmember Marti Emerald. "This was the heart of our concern about the pedicab industry, that ultimately somebody was going to be hurt or killed."

Emerald was part of a council committee that recently passed new regulations for pedicabs, including limiting the number of pedicabs operating downtown from 400 to 250.

Emerald said there are too many pedicabs and the overcrowding is dangerous. She also said she would like to require pedicab drivers to have California driver's licenses to show that they know the rules of the road. That would require a change in the state vehicle code.

Police said Safacinar did not have a California driver's license.

San Diego police Det. Dan Wall said Safacinar was driving Miller and a friend along the Martin Luther King Promenade, across from the Convention Center.

Police said pedicabs are not allowed there.

Miller was in town for the National Education Association convention with her husband.

Wall said Safacinar was driving in a serpentine pattern, apparently trying to give his riders a thrill.

The women asked him not to but he continued, and Miller was thrown from the pedicab, Wall said.
