REVERE – The Revere Police Department provided more details Tuesday about an alleged assault involving a handgun and a “Free Lodie” t-shirt that took place during the Columbus Day Parade on Broadway.Police arrested Pat Starkey, 32 and his wife, Heidi Picardi, 35, of 8 Atlas Ave., Saugus, in the incident. Starkey was wearing a black t-shirt with the words “Free Lodie” scrawled across it and was in possession of a handgun at the time of his arrest.Derek Lodie, 17, of Revere, is the only person officially charged in connection with the homicide of Revere Police Officer Daniel Talbot, 30, who died after being shot in the head while off-duty on Sept. 29. Lodie was charged with being an accessory to murder before the fact.According to the Suffolk County District Attorney’s Office, Lodie got into a confrontation with Talbot, three other off-duty Revere police officers and Talbot’s fiancĂ© while they were “socializing” in the ball field behind Revere High School around 1:30 a.m. Authorities say Lodie left the area and came back with three other young men – one of whom shot and killed Talbot.During the parade on Monday, additional officers rushed to the scene of the assault at about 3 p.m. for back up.The original officer had just thrown Starkey to the ground after he allegedly would not show his hands and continued to fight the officer, according to a police report.At the time, Starkey was wearing a shoulder holster containing a handgun, according an Item photographer.An officer, who was working crowd control because of the parade, became involved in the situation after Heidi Picardi approached him and said, according to a police report, “Officer, they just beat up my son. What are you going to do, just stand there?”When the officer approached, he noticed Starkey and another man arguing in the parking lot. The unidentified man then reportedly yelled, “Look, he has a gun!” pointing to Starkey.Starkey then refused to show his hands after being asked by the officer four different times, police said.During the scuffle, Starkey fell on top of the officer. When the two rose, the officer drew his weapon, according to police.At that point, Picardi allegedly pushed the officer and said, “Leave him alone.” She also allegedly pushed the officer after she was asked to stop interfering, police said.Starkey was charged with assault with a dangerous weapon, assault and battery on a police officer, disorderly conduct and resisting arrest. Picardi was also charged with assault and battery on a police officer, disorderly conduct and resisting arrest in addition to interfering with police business.Starkey phoned the Item Monday night and said the confrontation began after his stepson, Michael Picardi, 20, was wearing the “Free Lodie” t-shirt at the parade and was assaulted by an angry parade-watcher.Michael Picardi said Tuesday he was injured in the attack. Picardi was also taken into custody by police during the incident, but was immediately released without charges.Earlier in the afternoon, another police officer took two “Free Lodie” signs out of a front yard at 254 Cooledge St., which is part of the public housing projects.”He (a police officer) took it down and I said, ‘there’s going to be another one put up,'” said Amanda MacNeil, the resident who put up the sign.MacNeil said she was aware someone would be wearing a “Free Lodie” shirt at the parade. The 22-year-old mother also said Lodie was partying at her house the night of the homicide.Meanwhile, Revere police officers, still in mourning over Talbot’s death, were forced to hold in their emotions as they worked past Monday’s incident.”You have to handle yourself professionally as far as your feelings go,” said Police Chief Terence Reardon. But, “You have to wonder what goes through people’s minds.”
