Man arraigned in Mattapan shooting

A 21-year-old Dorchester man pleaded not guilty Thursday to charges that he shot another man in Mattapan on Wednesday afternoon.

Patrick Bishop was arraigned in Dorchester District Court on charges that included armed assault with intent to murder. Judge Jonathan Tynes set bail at $250,000 and ordered him placed under house arrest and GPS monitoring if he makes bail.

Assistant District Attorney Andrew Kettlewell said the victim, who was shot twice in the stomach, was “lucky to be alive.”

Bishop was out of view in the courtroom, speaking to the judge through an open door. His mother cried as prosecutors told the court about the condition of the alleged victim and the lengthy foot pursuit that led to Bishop’s arrest.

Kettlewell said in court that a “dispute over stolen property” may have led to the shooting, but did not elaborate.

“At this stage, motive remains under investigation,” said Suffolk district attorney’s spokesman Jake Wark.

Boston police said Wednesday on their website that the victim’s injuries were not life-threatening. But in court, Kettlewell said it was not clear until between 9 and 10 p.m. Wednesday that the victim, who was shot around 2 p.m., would survive.

Three men were having an argument on Fessenden Street in Mattapan outside a triple-decker Wednesday afternoon when Bishop shot one of the other men with a 9mm handgun, according to a police report filed in the case. Police found four 9mm shell casings at the scene.

Bishop told police that he was there, but that did not shoot the victim. He would not identify the shooter to police, saying, “I don’t want to give the name,” according to the police report.

Police said witnesses saw Bishop remove a gun from a backpack and return it to the bag before running away from the scene.

Bishop allegedly ran down Fessenden Street and then onto Norfolk Street, where he was confronted by a police officer.

Police found a black backpack nearby filled with clothes matching the suspect’s description. It also contained a handgun with an empty magazine and one round in the chamber, according to the police report. Bishop was arrested shortly after.

Bishop had been convicted in 2013 of unlawful possession of a firearm and possession of a firearm with a defaced serial number, prosecutors said.

In addition to the armed assault with intent to murder charge, Bishop faces charges of unlawful possession of a firearm, unlawful possession of a firearm in a second subsequent offense, unlawful possession of ammunition, carrying a loaded firearm, assault and battery by discharging a firearm, discharge of a firearm within 500 feet of a dwelling, and receiving stolen property.

The judge slated a probable cause hearing for Aug. 5.

Michelle Troiano, Bishop’s appointed defense attorney, said the defense is “in the process of doing their own investigation.”
