A Man Was Wanted in 5 Deaths Nationwide. It Turns Out an Alleged Victim Was His ‘Big Brother’ in 1985. Alberto Luperon Sean M. Lannon was his “Big Brother,” who mentored him in 1985. “I am happy to have Mike as my Big Brother,” the suspect said in 1985 about Michael Dabkowski, according a newsletter obtained by NJ.com. “He acts very nice and we do lots of things with him… We build boats, cars and things like that. We go a lot of places together. We play baseball and soccer with him and other things like croquet. I like him for a lot of reasons. It is a lot of fun with him. I hope he is elected as Big Brother of the Year.”
