Lawrence police were called May 16, 2007, by a man who said he found a pipe bomb hanging from the bottom of his truck.
In the plea, Parsons said the intended victim was dating his ex-girlfriend and had moved in with her.
Investigators found tools used to construct the bomb at the home of Parsons' family in Ellis County. They also found Internet searches for bomb building and recovered footage from Westlake Hardware in Hays of Parsons buying the materials.
