ROYAL OAK, Mich. -- A ghost bike has appeared along a stretch of Woodward Avenue in Royal Oak to memorialize a biker who was killed in a hit-and-run accident.

The mountain bike, painted in white, is chained to a street sign at Woodward and Linwood roads, where 40-year-old Jacqueline Robinson died.

Police said Robinson was dragged more than 100 feet at about 1:30 a.m. on Sept. 19.

"She didn't need to die like that—like an animal," said Robinson's cousin Lena Rice.

A nurse called 911 to report the incident, "There was a bike accident, there is a body" 911 tapes revealed.

Police are looking for the driver of a 2008 white Jeep Liberty who hit Robinson and sped away.

Lt. Corrigan O'Donohue said he is sure the hit-and-run driver knows they struck something and decided to flee anyway.

"I hope they have a heart, a soul and turn themselves in," said Rice.

Robinson leaves behind four children. She was buried on Thursday.

Ghost bikes are seen worldwide to remember victims who died on city streets.
