STAMFORD — A Stamford man who police say shot a semiautomatic pistol at passing cars on Interstate 95 Tuesday was charged Wednesday with multiple weapons offenses.

Steve St. Jacques, 26, of Durant Street, was charged with criminal possession of a firearm, unlawful discharge of a firearm, reckless endangerment and criminal trespass and was held on a $250,000 court appearance bond.

Police said St. Jacques was apparently suffering from paranoid delusions while high on a powerful hallucinogenic drug when he took to the Fairfield Avenue overpass and allegedly began firing down on cars.

“He went live on his Instagram account as he walked down the highway and talked about how he thought people were coming after him and he was shooting at them,” said Sgt. Sean Boeger, who headed up the investigation into the incident.

Police said they are familiar with St. Jacques. In 2014, he was charged with robbing $100 in birthday money from an autistic man. He was convicted of second-degree robbery and second-degree larceny.

No one has reported any injuries or damage following the shooting incident, police said. Investigators found four fresh shell casings on the Fairfield Avenue overpass shortly after a security guard at One Stamford Place called 911 to report a man shooting a firearm from the bridge at 12:08 p.m. Tuesday.

Police officers combed the thick brush on the steep embankment beside the thruway, with the aide of police dogs, in an attempt to collect evidence. Capt. Richard Conklin said their search netted unrelated items including a facsimile firearm — a BB gun of the type commonly used in street robberies because it appears authentic.

“This is not your average type of behavior where someone in the afternoon goes walking up on the freeway and starts clapping off rounds,” Conklin said. “During this situation with the pandemic we have found a sudden, a real flareup in the use of PCP, which makes people very paranoid.”

Lt. Eugene Dohmann said people on the highway early Tuesday afternoon were very lucky.

“When you fire four random rounds, even if you aren’t trying to hit someone, onto the highway with cars buzzing by — it was a miracle not one was struck,” Dohmann said. “We don’t know of any damage yet. A round may have hit a trunk of a car and they may not have heard it because of the highway noise — they may not have discovered the damage yet.”

Officers who responded to the call Tuesday found St. Jacques on the shoulder of the northbound side of I-95, taking off his clothing and flagging down cars, police said. Officers took him to Stamford Hospital.

At one point he told police that next time he would wait on the bridge and shoot at the police as they arrived, said Boeger.

Conklin said that a number of units in the department worked very well on Tuesday to make the apprehension and investigate the case.

“It was a very, very good collaborative effort between the Bureau of Criminal Investigations, patrol officers and narcotics officers during a frightening and distressing type of call and we were lucky no one was hurt,” Conklin said. “It was a quick response and congratulations to everyone involved.”
