Cameras record stabbing of 2 men at T station

Transit police asked for the public's help yesterday in identifying a man who attacked and stabbed two men inside the Park Street MBTA subway station a few hours after the Red Sox rally Monday at City Hall.

Acting police Chief Paul MacMillan said the Massachusetts Bay Transportation Authority's closed-circuit surveillance system captured images of the stabber and two accomplices, a man and a woman who also allegedly were involved in the attack on the two victims at around 11:45 p.m.

MacMillan said the suspects were videotaped as they entered the Government Center station at around 11:15 p.m., when they tried to evade the fare system, but were prevented from doing so by a T employee. At Park Street, another camera positioned at the far end of the southbound Red Line platform later captured the incident as it unfolded, he said.

"They did not know each other," MacMillan said of the combatants. "It was a spontaneous attack that occurred because they bumped into each other, words were exchanged, and the stabbing took place."

The recording showed the stabbing suspect as he fled, jumping down into the tracks behind a waiting train and then bolting up an emergency exit onto Boston Common, MacMillan said.

As he ran, he was recorded dropping a black-handled folding knife on the tracks and taking off a red sweatshirt. MacMillan displayed the blood-stained knife to reporters yesterday and said it will undergo forensic testing.

The man and woman who accompanied the stabber stayed at the station in the moments after the stabbing, but had fled by the time police arrived, he said.

MacMillan said the victims attended the Red Sox rally, but that he was not sure where they had been after the rally ended.

MacMillan declined to identify the victims because the suspects are still at large. He said one man is 19 and from Rockland and was expected to be released from Massachusetts General Hospital sometime yesterday. The second victim is a 20-year-old Abington resident who is expected to remain hospitalized for several days.

Both men were stabbed in the abdomen, MacMillan said.

MacMillan said violent crime has declined 16 percent on the MBTA system compared with the same time last year.

Anyone with information is asked to contact Transit Police at 617-222-1050.
