Mark Zimmerman was 44 years old when he was stabbed in Baltimore on Friday, June 4, 2010. The attack happened in the 6000 block of Moravia Park Drive. The Baltimore Police Department investigated his death, and the Baltimore Sun's homicide database lists it as a homicide.
Very little about Mark Zimmerman's life or death has been made public. A death notice published in the Baltimore Sun gave his full name as Mark Dean Zimmerman.
It said he died "[s]uddenly, on June 4, 2010," and described him as the "beloved son of Dolores M. (nee Hayes)." The rest of that notice, including any other relatives, his service arrangements or any details about his work and interests, was not part of the material reviewed for this story. No news article describing how he came to be stabbed could be found, and no memorial page or family fundraiser turned up in searches of his name.
Because so little has been released, even the basic circumstances remain unknown to the public. The record does not say whether he was stabbed during a fight or a robbery, attacked by a stranger or by someone he knew, or hurt indoors or on the street. It does not say what time of day it happened, whether he died at the scene or later at a hospital, whether anyone saw what happened, or whether investigators ever identified a suspect. Running lists of the city's 2010 homicides kept by local bloggers recorded his name, his age and the 6000 block of Moravia Park Drive, but listed no suspect next to his entry, while many of the killings around it on the same lists carried the name of a person charged.
Searching for him is made harder by how many other people share his name. Mark Zimmerman is a fairly common name, and searches turn up an FBI special agent in Maryland, a minor league pitcher, a Broadway actor and several other men of the same name who died in other states, none of whom have anything to do with this case.
Moravia Park Drive is a residential street in Baltimore, and the block where Mark Zimmerman was attacked was home to neighbors who may have noticed something unusual that Friday in early June. People who lived or worked nearby in 2010, or who knew him through his family, may hold pieces of the story that never reached the public record.
Baltimore recorded roughly 200 to 280 homicides a year between 2007 and 2014, one of the highest rates of any large American city, and many of those killings were never solved.
No arrest, criminal charge or court case connected to the death of Mark Zimmerman could be found in news archives or public records. More than 16 years later, there is no public sign that anyone has been held responsible. Someone who was on or near Moravia Park Drive in June 2010, or who heard Mark Zimmerman's name mentioned in connection with a stabbing that summer, may know something that could help. The people who loved him have waited years without any public answer about what happened to him. Even a small detail, such as a name overheard, a vehicle seen nearby or a conversation remembered, can help detectives move a case forward. Anyone with information can call Baltimore Police homicide detectives at 410-396-2100, or leave an anonymous tip with Metro Crime Stoppers of Maryland at 1-866-7LOCKUP (1-866-756-2587).
