For four days in July, a band of teenagers roamed the streets of Johnstown, Pennsylvania, and its suburbs in stolen cars, burglarizing homes and firing stolen handguns, police said.

Only now are authorities coming to grips with the totality of the crime spree that reached at least seven municipalities.

“These kids want to be gangsters,” Richland, Pennsylvania, Police Det. Thomas Keirn said. “They want to be the baddest of the bad. They got together and decided they were just going to go crazy, and for four nights, they did.”

Authorities on Wednesday charged the seven teens, a group of mostly 14- and 15-year-olds, with a range of felonies including vehicle theft, minors possessing firearms, receiving stolen property and prowling at nighttime.

Because of their ages, they won’t be publicly identified. 

One of the teens is accused of firing shots from a stolen firearm at two houses in Richland as the residents slept. No one was injured.

“He found two houses of people who he didn’t like and fired at them – ‘boom, boom boom,’ ” Keirn said. “We have a Facebook picture of him standing in front of a Sheetz store with two stolen handguns.”

The crime spree began on July 14, spreading from Johnstown to its suburbs as the teens entered more than 100 unlocked vehicles to steal electronics, money and firearms, Keirn said. 

Police said the four stolen vehicles, which were left unlocked with the keys inside, were recovered. The teens caused more than $6,000 total damage to two of the vehicles.

Richland police have not found two stolen firearms, a .22-caliber firearm and a .45-caliber firearm, which the suspects fired in wooded areas.

Keirn said some of the teens had been “significantly involved with juvenile probation” previous to the crime spree.

“These kids are brain-dead, man,” Keirn said.”They have no moral fiber whatsoever, none.”
