A Northampton woman and a former junior firefighter already charged with setting multiple barn fires in the area have now been charged with causing several vehicle fires.

Samantha Keeney, 24, and Justin Emmons, 19, both of Northampton, waived their preliminary hearings May 22 on charges related to two fires in Lehigh Township and one in Allen Township.

Both face three counts each of arson; causing a catastrophe; reckless burning; criminal mischief; and criminal trespass for those incidents.

Emmons faces an additional three counts of reckless endangerment and conspiracy, as well as a single count of agricultural vandalism.

Keeney also faces one count of reckless endangerment and three counts of agricultural vandalism.

Keeney was charged April 4 in connection with the barn fires at 3646 Cedar Drive and 786 Fir Drive in Lehigh Township and 4413 Cherryville Road, Allen Township.

Emmons was taken into custody April 5 on a traffic stop by Pennridge Regional Police Department.

Keeney has been held in lieu of $270,000 bail, while Emmons has been held in lieu of $120,000 bail in the fire cases.

On May 22, Northampton Borough Police filed reckless burning and other charges against Keeney and Emmons for their alleged roles in a March 23 car fire and a March 29 truck fire in the borough.

According to the affidavit of probable cause filed by Detective Glenn Deist, of the Northampton Borough Police Department:

At 5:06 a.m. March 23, officers responded to a working vehicle fire in the area of the 400 block of East 10th Street. A silver 2015 Dodge Dart had three flat tires at the time that appeared to be punctured.

At 3:25 a.m. March 29, officers responded to a second vehicle, a white 1999 Ford F-250, on fire at the same address. The fire also involved the side of a garage the vehicle was parked next to.

Emmons knew both owners of the vehicles.

Emmons told police Keeney was the one setting the fires and she set the truck on fire.

At the time of the truck fire, Emmons was scheduled for a polygraph test, but he failed to appear for the interview.

Keeney, who was eventually arrested by state police for the barn fires, was interviewed and said she set the truck on fire and Emmons set the car on fire, as well as cutting three of the tires on the car and one on the truck.

On the vehicle fires, both face charges of reckless burning, criminal mischief and recklessly endangering another person. They remain incarcerated in Northampton County Prison in lieu of $20,000 bail.

They are scheduled to appear for a preliminary hearing on the new charges June 5 before Magisterial District Judge Robert Hawke, of Walnutport.
