Salt Lake City police are asking the public for help locating any relatives of a cyclist who died Monday after being struck by a vehicle whose driver went into diabetic shock.

Sidney Mabine, 58, was riding a bicycle along State Street at 1385 South about 4 p.m. when a motorist struck him. He suffered head and internal injuries.

Mabine, who appears to have come to Utah from Virginia, was living near 700 East and 300 South. He worked in Utah as an independent contractor for the trucking firm C.R. England from August to October last year, but it is unclear whether he was employed at the time of his death.

He also may have lived in North Carolina.

Mabine was riding north with traffic on State Street when he was struck. He was not wearing a helmet, but his injuries were so extensive that one likely would not have prevented his death, a police spokeswoman said.

The driver, 51, continued driving north until an officer pulled her over at 1300 South, police said. She was "totally incoherent" and did not realize she had hit the cyclist.

The driver who hit Mabine had a blood glucose level of 32 milligrams/deciliter at the time of the crash; the normal range is 70 to 140.

Diabetes is a condition that, depending on its severity, can result in driving restrictions. Police, who have not released the driver's name, say she did have a valid driver license. The crash remains under investigation.

Meanwhile, anyone with information about Mabine is asked to contact the Salt Lake City Police Department at (801) 799-3000.
