The alleged motive in a Des Moines arson case is tied to actions on Facebook, a social networking site, according to police. Detectives have arrested Jennifer Christine Harris, 30, of Des Moines, on a charge of first-degree arson. She is being held in the Polk County Jail on $100,000 bond. The fire broke out in a garage at the Jim and Nikki Rasmussen residence, 2351 E. 40th Court on Oct. 27. Officials said the fire at 1 a.m., caused a popping sound and then a “boom.” The family was sleeping at the time but the sounds alerted family members to the danger. They managed to escape as the siding on their house began to melt from the heat of the fire in the detached garage. [...] A police report says that when an officer asked Nikki Rasmussen about Jen Harris, Rasmussen said “… the two are no longer friends due to a dispute over Facebook. According to Nikki, Jen is angry with her because she ended their friendship on Facebook.” More... It's - a - stupid - website! A website! It's not the end of the world!
