Michael Dabkowski, 66, was bludgeoned to death with a hammer inside his East Greenwich, New Jersey, home on March 8, 2021. The investigation quickly focused on Sean M. Lannon, then 47, a former mentee from the Big Brothers Big Sisters program who fled the state in Dabkowski’s car and was arrested in St. Louis on March 10, 2021.

Lannon told investigators he had been sexually abused by Dabkowski as a child and said he went to the house to retrieve photographic evidence; no such evidence was introduced in court. Lannon later pleaded guilty to first-degree murder in New Jersey and received a 35-year sentence, with at least 30 years to be served before parole eligibility. He is also implicated in multiple deaths in New Mexico and has made unverified claims of responsibility for additional killings, with further charges pending there.

Were there contacts, records, or acquaintances in New Jersey who knew Dabkowski and might shed light on his relationship with Lannon?
