Sorry, hope my description of the area didn't hit too close to home.
If it's any consolation, I recently learned that a childhood neighbor's house (less than a block from my home) was a "known drug center" at the time, possibly part of a biker gang -- and found that out the same way my family and friends did: when the police excavated the basement as part of a 28-year cold case homicide investigation.
(The case is actually fascinating, with a couple odd twists including the house being owned by a judge, and the tenant being the prime suspect's sister.

The day I found out ... let's just say I might have freaked out a little.
