On the evening of March 4, 2015, Michelle Cox, 41 and a mother of five, was walking home from a store in her Bronx neighborhood. As she entered the stairwell of her Webster Avenue apartment building around 10 p.m., she was fatally shot in the back of the head and pronounced dead at the scene. Family members described her as harmless and nice and have long sought answers and justice.

For nearly nine years there were no arrests and the investigation appeared to have stalled, leaving family members feeling neglected and desperate for a breakthrough. In January 2024 the NYPD arrested Lasalle Herman, 34, and charged him with Cox’s murder; he was awaiting arraignment in Bronx Criminal Court on the murder charge.

What can anyone who knew Michelle, her movements that night, or activity in that stairwell tell investigators?
