A number of bodies have been found in the waters around Baltimore's Inner Harbor in recent months.
Police and the state medical examiner's office have not reported signs of foul play in any of the cases, with alcohol as a factor in several of them, though answers on what exactly occurred remain elusive.
"The majority of the cases that we've looked at, it appears that alcohol has played a factor," Det. Jeremy Silbert said in a recent interview. "Certainly with all these cases, we work very closely with the medical examiner's office and look over every clue to ensure we do a complete investigation."
Only one case in recent years has been ruled a homicide, and it took two years for investigators to learn what had transpired. Ankush Gupta, 22, fell into the waters near Harborplace in April 2008 while passing through with friends. No one saw what happened, and surveillance cameras didn't pick it up. But two years later police received a tip that Wayne Black, of Pasadena, had approached Gupta asking for a cigarette and shoved him in. Black received four years in prison after pleading guilty to involuntary manslaughter.
