RICHMOND, Mich. -

Richmond police say they are investigating whether a woman who is accused of causing a fatal accident last week was under the influence of drugs.

Kimmel was killed.

Police said prescription drugs were found in Fistler’s car, but toxicology reports will be used to make a final determination.
