A Boston police officer has been arrested by his own department, charged in connection with the shooting of his wife Monday afternoon and for allegedly misleading investigators about what happened.

Korey Franklin, 32, of Hyde Park was arraigned this afternoon in West Roxbury District Court on charges of reckless assault and battery by means of a dangerous weapon, discharging a firearm within 500 feet of a dwelling and misleading an investigation. He pleaded not guilty.

Police told the Herald Monday and Tuesday the woman’s gunshot wound was self-inflicted, repeating today in a statement, “Initial indications from the scene suggested the injury was sustained due to a self-inflicted accidental discharge.”

“We take this incident, and all incidents that involve police officers, very seriously,” Commissioner William G. Gross said. “This arrest clearly shows that the Boston Police Department has the ability to police ourselves and that we hold our officers to the same standards as the citizens we serve and protect.”

Police went to the couple’s house shortly after 1 p.m. Christmas Eve and found the wife injured inside the home. They later determined Franklin, who police said was off-duty at the time of the incident, “was responsible for the discharge of his personal weapon and the resulting injuries.”

Judge Lisa Ann Grant released Franklin on his own recognizance and ordered that he stay away from the woman, surrender all firearms, and not leave the state without the approval of probation officers. Assistant District Attorney Ian Polumbaum had pushed for a $5,000 bail.

Boston Police ordered that Franklin undergo a mental health evaluation.
