NEW YORK (AP) _ Police questioned a man Sunday in the killings of six people in an apartment, and investigators focused on drugs, revenge and robbery as possible motives.

The victims, including two teen-age girls and their mother, were found stabbed or shot early Saturday in a condominium in a quiet, residential section of the borough of Queens.

The bodies were found after a seventh victim, a woman slashed in the throat and shot, escaped by jumping from a second-floor balcony. She couldn't talk but later wrote a note in the hospital directing police to the apartment.

The man being questioned had not been arrested, police Lt. Ray Ferrari said.

The victims were all of Colombian background, police said. One had been in the United States for two months, but the status of the others was not known.

``A drug-related crime is one theory,'' said Officer Scott Bloch, a police spokesman. ``Also revenge or robbery. Nothing is being ruled out as of now.''

No drugs or drug paraphernalia were found in the apartment, but neighbors told police there were many people coming and going, a possible indication of drug dealing.

Police responding to a 911 call about 3 a.m. Saturday found the wounded woman on the front lawn of the apartment building. Police initially didn't know where she had come from and took her to the hospital. Eight hours later she was able to write the note and police returned to find the bodies.

The woman, whose name was withheld, was in critical condition Sunday.

In addition to the woman and her daughters, police identified the victims as the woman's common-law husband, his cousin, and a teen-age friend. All had been stabbed or shot, Queens Chief of Detectives Ray Abruzzi said. All except the friend lived in the apartment.

Neighbors told police they heard no shots or other strange noises coming from the apartment. Police Commissioner William Bratton said police found no sign of forced entry.
