Highland Park gunman Robert Crimo contemplated second shooting: authorities

The Highland Park Fourth of July gunman confessed to cops that he slaughtered innocent parade-goers — and that he “seriously contemplated” shooting up another celebration later, officials said Wednesday.

Robert E. “Bobby” Crimo III, 21, allegedly had another rifle and approximately 60 rounds on him when he fled Highland Park after allegedly killing seven and injuring more than 40 others on Monday.

He then drove towards the Madison, Wisconsin, area in his mother’s car — but returned to Illinois, where he was later nabbed, after deciding he wasn’t fully prepared to pull off the second shooting, according to authorities.
