LOWELL -- As police Officer Scott Merrill entered the bathroom of the fifth-floor apartment on Dutton Street on Tuesday, he said he observed a Groton man shooting "a brown liquid" into his forearm.
Police say Gregory Tammaro grabbed another syringe, drew his own blood, pulled it from his arm and told Merrill "I have AIDS." A struggle ensued.
In Lowell District Court on Wednesday, Tammaro, of 26 Valleria Drive, Groton, pleaded not guilty to charges of assault to murder, assault with a dangerous weapon, possession of a class A drug and resisting arrest.
He was held on $3,000 cash bail. Judge Barbara Pearson also ordered that Tammaro's bail be revoked on several pending cases, keeping Tammaro behind bars. A probable-cause hearing is scheduled for May 8.
A resident of the building called police about 5 p.m. on Tuesday to report a man laying in the hallway with blood streaming down his arms. The resident said the man seemed disoriented and asked for two different unit numbers. Apartment units are accessible during the day by elevator.
Police said Tammaro then knocked on an apartment door, asking if he could use the bathroom. The resident told police she let him Tammaro in because her husband knew Tammaro from a 12-step recovery meeting several months earlier.
Emergency personnel had to force the bathroom door open, police said. Merrill subdued Tammaro with two shots of chemical spray, reports state.
Tammaro was transported to Lowell General Hospital for a medical evaluation and then released into police custody.
