Uncle of Highland Park shooting suspect said he saw 'no signs of trouble' in his nephew

• The uncle of the Highland Park shooting suspect said he "saw no signs of trouble" in his nephew.
• "If I did see signs, I would have said something," Paul Crimo said.

The uncle of the suspect in Monday's mass shooting at Chicago's Highland Park said he saw no warning signs in his nephew's behavior prior to the incident.

Paul Crimo spoke to Fox 32 Chicago on Monday about his nephew, 22-year-old Robert Crimo, who was arrested over the incident that left at least six people dead and dozens injured.

Crimo told the outlet that his nephew lived with him in the same house but in separate quarters and that the two barely interacted.

When asked if he had spotted any red flags in his nephew's behavior, Crimo said he saw none.

"There's been no warning signs," he told the outlet. "I saw him yesterday evening and when I went home, I said, 'Hi' to him. And then when I came back downstairs, I said, 'Bye,' he said, 'Bye.' And that was it."

"I see nothing that would trigger him doing this," added Crimo, who told the outlet that he didn't know where his nephew could have obtained the weapon in the shooting.

"I saw no signs of trouble. And if I didn't see signs, I would have said something. But there were no signs of trouble," Crimo said.

He also told Fox 32 Chicago that his nephew was a "YouTube rapper" and had been unemployed for at least two years. He described the younger Crimo as a "real quiet kid" who kept to himself and spent a lot of time on his computer.

Crimo claimed that he and his brother, the shooting suspect's father, were "very well known" in the Highland Park community.

"I'm deeply sorry for everyone that lost their lives and got injured. From the bottom of my heart, I'm heartbroken, and my heart is shattered to hear this," Crimo said.
