We thought "he ran into my knife" was an excuse you only heard in the "Cell Block Tango" but what do you know, that is exactly the argument that the lawyer for James Parker, 59, is using in Staten Island. Parker is accused of fatally stabbing his daughter's boyfriend to death early Monday morning.

Yesterday, after Parker was arraigned, his lawyer Louis Diamond explained what he thinks happened in the early hours of the week at Henry Raftrey's Sunnyside home. According to Diamond, Raftrey was "on a bender" and the two men were fighting over child care for a child Raftrey had fathered with Parker's daughter:

"There's a third guy there," he said, referring to a friend of Raftrey, who a police source said on Monday was also present. Diamond wouldn't give the man's name to reporters Tuesday.

According to Diamond, Raftrey and the friend—who the attorney described as 6 feet 7 inches tall—threatened Parker when in the house's attic. Parker went up to the attic a second time, knife in hand, and said, 'Listen, I don't want any trouble, just leave her alone,'" Diamond said.

That's when, according to Diamond, the friend got up out of a chair and pushed Raftrey toward Parker. Raftrey "ran into the knife," Diamond said. "My client didn't stab anybody."

It seems nobody is denying that Parker stabbed his daughter's ex. When police arrived at Raftrey's house on Monday morning they found Parker still holding the knife in his hands, according to the Staten Island District Attorney's office. Parker was charged with second-degree murder and fourth-degree criminal possession of a weapon and yesterday was ordered held without bail until his next court appearance Friday.
