HIGHLAND PARK, Ill. – Prosecutors charged the suspected gunman in the shooting rampage at a Fourth of July parade in this Chicago suburb with seven counts of first-degree murder Tuesday, hoping to put him behind bars for the rest of his life.

Lake County State’s Attorney Eric Rinehart said that, if convicted, Robert E. “Bobby” Crimo III faces a mandatory sentence of life in prison without the possibility of parole.

“These are just the first of many charges that will be filed against Mr. Crimo,” Rinehart said. “I want to emphasize that. There will be more charges. We anticipate dozens of more charges.”

Police said Crimo fired more than 70 shots from a rooftop Monday, killing seven people and wounding nearly 40 more with a legally purchased assault rifle before fleeing. He was captured that evening after an intense manhunt. 

Latest developments:

►Investigators have interrogated the suspect and reviewed his social media posts but provided no motive for the attack, describing it only as “random.”

►Lake County Deputy Chief Christopher Covelli said the gun – “similar to an AR-15” – was legally purchased by Crimo in the Chicago area.

Hundreds gather for vigil the day after shooting

Hundreds of people congregated in downtown Highland Park Tuesday evening, blocks from the scene of the shooting. Families, neighbors and friends held hands, hugged and cried. Others laughed and smiled as they unexpectedly bumped into loved ones.

“It’s good to face your fear and come back to the scene. There’s something about coming back,” said Elise Dayan, 54, a 21-year resident of Highland Park.

Some exchanged stories of where they were during the parade. Some hung orange ribbons—for gun safety—in the trees. Others placed flowers, prayed and lit candles. Many kids wore Highland Park High School shirts and sweatshirts.
