Three brothers and a juvenile friend chose to liven up their summer nights by throwing eggs at parked cars and houses on Pekin’s north side, police said Monday.

They didn’t stop at a carton or two. The four allegedly pelted more than 350 targets over two weeks along more than a half-dozen streets.

Knowing they had to buy their ammunition somewhere, officers found security video and photos of two of the suspects recently buying 120 eggs at the Walmart Supercenter.

“Please help us identify and locate these vandals so we can have a chat,” police Public Information Officer Billie Ingles asked the public through her department’s Facebook page Sunday morning, after residents awoke to discover the latest of seven overnight eggings.

Within a few hours, the four were in custody.

Arrested for misdemeanor criminal damage to property were Ryan Jack, 23, of Creve Coeur, Christopher Jack, 19, and Dakota Jack, 18, both of East Peoria. The fourth suspect, 17, was referred to juvenile court.

“Their dad brought them in” Sunday afternoon, Ingles said of the three brothers.

That happened after the department received numerous Facebook replies from people who recognized the egg buyers in the Walmart photos, she said. “We got a lot of calls” as well.

The suspects had no specific motive for their vandalism other than “just wanting something to do,” and targeted no one’s car or home individually, Ingles said. Multiple victims, however, were egged more than once.

“They were just driving and throwing,” she said.

Most of the damage took place along and around Redwood Drive, Hawthorne Avenue, Cypress Street, Pine Street, Linden Street and Maple Park Drive.

The Jack brothers are expected to be formally charged when they appear in bonding court Tuesday.
