JAMESTOWN — A Jamestown man has been charged with second-degree criminal possession of a weapon as Jamestown police continue their investigation into three shootings Friday and Saturday.

The first incident was early Friday morning. The victim of that incident was at a downtown establishment and had a confrontation with another individual after leaving. The victim has been transported to an out of town hospital with life threatening injuries.

Then, later Friday, Jamestown officers on patrol responded to the 800 block of Prendergast Avenue for a report of a victim of a gunshot with minor injures. The person was treated and released with non-life threatening injuries. The investigation is continuing at this time.

Around 1 a.m. Saturday city police officers responded to Victoria Avenue for another report of a gunshot complaint in which one person was taken to an out-of-town hospital for treatment of life-threatening injuries. As a result of the third investigation, Juan A. Tufino Jr. was found to be in possession of a loaded pistol. He was charged with second-degree criminal possession of a weapon and taken to the Jamestown City Jail until he could be arraigned.

“The investigations into all of these incidents are continuing,” the Jamestown Police Department said in a news release Saturday. “All incidents are believed to be targeted incidents where the offender knew the victim.”

Anyone with information about any of these incidents is asked to contact the Jamestown Police Department at 716-483-7537 or the confidential tip line at 716-483-TIPS (8477).

Jamestown police aren’t releasing the name of any of the victims in the shootings yet.

Tufino has been charged several times in the past, according to a search of The Post-Journal archives.

In December, he was charged with second-degree criminal possession of a weapon, resisting arrest, seventh-degree criminal possession of a controlled substance and nine counts of reckless endangerment after police officers saw Tufino inside a North Main Street store knowing he had active arrest warrants. According to a police report, Tufino reportedly refused to comply and was eventually taken into custody after a brief struggle.

Twice in 2017 Tufino was charged. In July 2017, Tufino was charged after police responded to a report of a man who allegedly pointed a gun at another person. Police report the caller in the incident identified Tufino as the person with the gun.

During a safety check of the apartment, officers reported finding Tufino in a back bedroom. He was charged initially with violating a valid order of protection from Jamestown City Court to stay away from the apartment. Jamestown police report receiving limited cooperation from the people who live in the apartment, so they obtained a search warrant from Jamestown City Court. During the search, officers found two loaded handguns, heroin, cocaine and a large quantity of drug-packing materials. As a result, Tufino was charged with multiple counts of endangering the welfare of a child, two counts of third-degree criminal possession of a controlled substance (heroin), third-degree criminal possession of a controlled substance (cocaine), fourth-degree criminal possession of a controlled substance, obstructing governmental administration and criminally using drug paraphernalia.

In June 2017, Tufino was charged with second-degree menacing and third-degree assault after police officers responded to a reported domestic dispute. Tufino allegedly bit a woman and hit her in the head with a gun at a Lafayette Street residence.
