SANCHEZ: A New Jersey teenager is in police custody this morning after four people were found shot to death in his parents' home. Both of the suspect's parents, his sister and family acquaintance were found last night when police responded to a 911 call reporting shots had been fired. CNN correspondent, Polo Sandoval is live in New York with more. Polo, what do we know?</s>POLO SANDOVAL, CNN CORRESPONDENT: Well, Boris, get you caught up with what we do know at this point. Investigators in New Jersey are treating this as a domestic incident. That's how they're investigating this. We understand according to information released by authorities that police were called to a home there in Long Branch, New Jersey, just before midnight last night. They arrived to find four people had been killed there, a married couple by the name of Linda and Steven Kologi, also their 18-year-old daughter Britany, and a 70-year-old family friend by the name of Mary Schultz. All of them had been shot and killed inside that home. They also arrested the 16-year-old son of that murdered couple. At this point, there's still a lot of unanswered questions in this case. Obviously, a motive, the big question as to why this could have happened, is being investigated right now.
