The suspect in the shooting in Highland Park, Ill., had his house frequently visited by law enforcement.

There were allegations of both verbal and physical abuse in the police records.

In one of the police reports dating back to 2010, he claimed that Pesina had hit him with a screwdriver, but later refused to add that to his statement.

He claimed she hit him with a shoe.

According to the August 2010 report, an argument began because of their failing relationship after he said he came home to find his wife drunk.

Pesina told police that she was upset from an incident earlier in the day when she was disrespected and belittled by a man.

There were episodes of intoxication and arguments. There were no arrests in relation to the reports of harassment from a neighbor.

The suspect in the Fourth of July shooting, which left at least seven dead, threatened to kill everyone at his house in September, leading police to arrive and seize knives he had collected.

A consent form for his son to apply for gun ownership was signed by his father, who is now under investigation for the shooting.

His son legally obtained five guns despite threatening to kill family members and attempting suicide, despite his father sponsoring his firearm owner ID application.
