Police tape still marks the Beloit home on Sunshine Lane where the unthinkable happened early in the morning. Inside police say Bruce Hemmy, 58, was killed by his son Peter.
Next door, Denise Isabell says she's not surprised.
"He was really, really strange. He was really weird. He did a lot of weird things. He'll talk to the grass and the lawnmower and just say stuff like you can't beat me and I’m going to win, and just really weird stuff all the time," Isabell explained.
Detectives say after allegedly killing his father, Peter Hemmy walked right into the police station and confessed.
"It does make the investigation run smoother, however there is still many people to speak to, there will be medical reports, it will be awhile before it's all wrapped up," Beloit Police Captain Dan Risse, said.
As investigators pour through evidence, back on Sunshine Lane Denise Isabell wonders what made her neighbor snap.
"We never heard anything like arguing or anything coming from that house so, besides him doing it to himself and beating up the door and stuff like that," Isabell said.
An autopsy is scheduled for Tuesday.
Police won't say how Hemmy was killed, but detectives say he was not shot.
