A 35-year-old man has been sentenced to nearly nine years in prison for stalking his ex-girlfriend and her family and lighting a car on fire.
Gregg Pfeifer was also sentenced Friday to lifetime probation, Maricopa County prosecutors said.
According to court paperwork, Pfeifer began stalking and harassing his ex-girlfriend as well as her family at their home in July 2011.
The victims filed a restraining order against Pfeifer the same month.
Police found Pfeifer then harassed the victims through phone calls, text messages, email and driving by their home.
"He would call her 100 times a day and text her 100 times a day," said Dotti Hetzell, whose daughter was stalked.
Police say this led the victims to change their phone numbers, cancel their Facebook and email accounts as well as install a $2,000 surveillance camera system.
"We never knew what time of day or night he would come around, he would slash tires," Hetzell said.
Police say the violence increased to allegations of slashing tires, throwing rocks at the home and arson.
On Dec. 27, 2011, police say Pfeifer allegedly put a bottle of gasoline on the hood of the victim's boyfriend's vehicle, which was parked only three feet from the house where a 5-year-old child was sleeping. One of the victims saw the fire and quickly sprayed down the truck to keep the flames from reaching the home.
