Authorities have arrested a suspect in the case of an alleged police impersonator.

James D. Willie is believed to have killed two motorists in Mississippi.

Willie was arrested and the 9-milameter handgun authorities say was used in two recent highway shootings was in his possession.

The arrest may put an end to a case that caused a massive manhunt by law enforcement and created panic and fear for many drivers throughout Mississippi.

Investigators with the Mississippi bureau of investigation had raised the possibility that someone posing as a police officer is to blame for the shooting deaths of 74-year-old Tom Schlender and 48-year-old Lori Anne Carswell, which happened 55 miles apart.

Willie was arrested on Tuesday on an unrelated offense.
