While a big out-door Tammany meeting was being held at First Avenue and One Hundred and Fifteenth Street last evening, the speaker was interrupted by the wild shrieks of pain and rage of a man who had just been stabbed by a jealous rival. The wounded man was Michael Carpiella, thirty-two years old, of Bridgeport, Conn., and his assailant was Louis Phillepele of 2,242 First Avenue.

The woman over whom the affray occurred was Lucia Roccio, who lives with her parents at 2,177 First Avenue. Phillepele has been calling upon her for some time, and was greatly angered a few days ago when he learned that she was corresponding with Carpiella, who had arranged to come to see her yesterday.

Phillepele loitered about the entrance to the house in which the young woman lives for several hours until Carpiella appeared. He spoke to him as soon as he came in sight, and the two were soon engaged in a fierce dispute. they walked toward the meeting, and just as they were on, the outskirts of the crowd, blows were exchanged, and then Phillepele drew a knife and plunged it into Carpiella's abdomen.

The victim ran down First Avenue, holding his hands over the wound and shouting for help. Policeman Kumpf of the East One Hundred and Fourth Street Station was the first to join in the pursuit of Phillepele, but nearly every one at the meeting was close upon his heels. They followed the man into 2244 First Avenue, and the policeman went to the scuttle, but Phillepele fled over the roof and went down through No. 2246 to the yard; there he climbed the fence into the yard of No. 2248.

The policeman went over after him, and Phillepele drew his revolver. The policeman had his weapon leveled first, and, seeing this, the man surrendered.

Carpiella was cared for on the sidewalk by Policeman Ward until an ambulance came and took him to the Harlem Hospital. The doctors there said his injuries were very dangerous and that an operation would have to be performed as soon as he rallied from the shock.

Phillepele admitted the stabbing at the station house, but said he had used the knife because the other man had tried to shoot him with a revolver. No weapon was found on the wounded man.
