JACKSONVILLE, Fla. (AP) - A Jacksonville good Samaritan was electrocuted when he touched a power line downed in a traffic accident.

David Katterhenry had stopped to help a 19-year-old pregnant woman who had swerved to miss a deer and hit a power pole, breaking it in half.

Police say the 52-year-old engineer stepped on a power line and was killed instantly.

The Florida Times-Union reported that Katterhenry and his girlfriend had been on their way to a fishing trip when they came upon the wreck Saturday morning. The teen driver did not appear to suffer serious injuries.
