Sgt. Peter Foltz, 45, was a 20-year veteran of the department, a thoughtful, thorough professional, Kenner Police Chief Keith Conley said Thursday.
It appears that Foltz suffered a medical emergency while driving westbound on the Expressway, and pulled over to the side of the roadway, NOLA.com reports.
An off-duty Gretna police officer spotted the vehicle and stopped to check on the driver. The officer called for emergency services and New Orleans police after realizing that Foltz was in distress, authorities said.
Sgt. Foltz could not be revived.
