Suburban home invasion that started as a Grindr hook-up may have links to similar crimes in Chicago city: source

CHICAGO — A suburban Christian school teacher has been jailed after prosecutors accused him of using the gay dating app Grindr to target a suburban man for a violent home invasion. Chicago police believe Antoine Perteet is responsible for similar crimes in the city, and Cook County prosecutors charged him with one of those last week.

The city case occurred in the 1900 block of West Morse late on June 28, according to CPD records. He’s charged with armed robbery with a firearm and aggravated unlawful restraint.

But we have more details about the suburban case. There, Perteet, 33, is charged with home invasion, kidnapping, possessing a stolen firearm, and unlawful use of a weapon by a felon in connection with a Grindr date that went bad in Cicero on October 8.

During a recent detention hearing, prosecutor Matthew Larkin told Judge Susana Ortiz that Perteet connected with the victim on and before the date of the attack via a dating application, which our source identified as Grindr. During those conversations, the victim provided his home address so they could meet, Larkin said.

On the day of the home invasion, the victim was walking his dog in front of his Cicero home when Perteet and another person arrived in Perteet’s car, Larkin said, according to a transcript of the detention hearing.

Perteet allegedly raised his shirt to expose a handgun and led the victim inside. He forced the man to lie face down in the bedroom as the second person entered the apartment, Larkin continued. The pair forced the victim to unlock his phone and bank accounts.

As the men went through the phone, Perteet allegedly put his foot on the man’s face and told him not to look up.

He and the accomplice restrained the victim’s legs and arms with belts, placed painter’s tape on his eyes, and stuffed a towel in his mouth, Larkin alleged. Both men went through the victim’s home searching for valuables, eventually leaving with a container of coins, about $50 cash, the victim’s phone, smartwatch, and his keys, said Larkin.

The victim eventually freed himself and called 911. Cicero police found surveillance video showing what happened outside the man’s home. According to Larkin, a license plate reader put Perteet’s car in the area at the time of the home invasion, as did Perteet’s phone data. However, the victim was unable to identify Perteet in a photo line-up.

Rosemont police pulled Perteet over the next day. During a search of his car, the cops found a black face mask and gray hoodie similar to those worn by one of the home invaders, Larkin said. They also found ammunition and a stolen 9-millimeter handgun, but they released him without charges, according to Larkin.

A specialized police unit arrested Perteet at a suburban Christian school where, according to his attorney, Ari Williams, he worked as a gym teacher and fulfilled “multiple roles.”

Williams argued against detaining Perteet, according to the transcript, pointing to a lack of physical evidence and the fact that Perteet had gone ten years without being arrested. She said he is married with four children.

Larkin said his most recent conviction was a 2013 theft in Lake County that resulted in a four-year prison sentence. Before that, Perteet was convicted of burglary and attempted burglary in 2008. Those cases resulted in probation.

Chicago police have eyed Perteet in connection with a string of Grindr-related robberies, including some that they warned the public about last year, according to a law enforcement source.

Last spring, at least 15 men were lured to the 1800 and 1900 blocks of South Springfield by someone they met on Grindr. Most of those victims were directed to abandoned homes, where they were robbed. Some were tied up by a gunman who forced them to surrender phone and banking information, according to CPD reports.
