Tyler Lynn-Gainous was 21 when he was found dead from a gunshot on a sidewalk along Weaver Drive in Virginia Beach on May 27, 2011. Neighbors who knew him after his move from New Jersey remembered him as kind and helpful. The shooting followed an argument earlier in the week that investigators tied to a heated exchange in the street near the Aden Park Apartments; witnesses described a man using profanity around the time of the incident.

Police focused on a neighbor in the same apartment complex and took him into custody for questioning. Michael Jemar McLean, 32 and living in Virginia Beach, was arrested and charged with murder and use of a firearm in the commission of a felony. Mental health evaluations later played a decisive role in the court proceedings.

Did anyone in the neighborhood have contact with Tyler in the days before May 27 or recall the argument that preceded the shooting?
