GREEN BAY, WI (WTAQ) - A federal jury in Green Bay has found Francis Grady guilty of arson and damage to property after he smashed a window and started a small fire inside a Planned Parenthood clinic.

In the one-day trial, Grady took the stand and admitted to setting the blaze at the clinic in Grand Chute April 1st. But testified he felt his intention can't be defined as arson.

The Kaukauna man said he wanted to, "release the souls of the children," who had died in the clinic and, "give them their last rites."

According to FOX 11, Grady claimed he may have been high on gasoline fumes that spilled onto his jacket when filling up the small water bottle with gasoline before heading to the clinic.

Grady testified he'd "thought of those poor children for years." He said it was a spur-of-the-moment decision to spark the fire. He said it came to him the afternoon of April 1, while at his friend's house.

Earlier in the day, prosecutors showed a videotape of an interview with FBI investigators, in which Grady said, "I lit the clinic up. Just a little bit. There ain’t no damage to it."

Grady faces up to 21 years in federal prison.
