Maybe not in Incel, but there had to have been trouble in the family for a long time. He was at his girlfriends the afternoon of the murders. He told her he would be visiting his family for pizza night. Then all this carnage happened.
He left the murder weapon, an AR-15 Rifle, at the scene of the crime. Cops found the black rifle lying on the floor of the entryway. Seems that he didn’t even try to cover up very much. Probably severe mental disorders. Bad Seed Syndrome.
His slain family were well known and liked in that community.
***Probably severe mental disorders.***
Ever notice that when the mental hospitals were closed down in the 1970s and the inmates dumped on the streets that mass murders took off like a rocket?
And he used an(GASP) AR-15! It might not have been so bad if he had used a Remington model 8 made in 1903!
