UNSOLVED: Search for suspects in brutal killings of 4 local women

Bonnie Black, Palak Bhadreshkumar Patel, Tamara Gliss and Charnice Milton all have something in common. The four women were murdered in either D.C., Maryland or Virginia over the last few months. Two of them were mothers. Their cases are not connected, but all of them remain wide open. Police are still searching for suspects and answers in their brutal deaths. Here are their stories:

Bonnie Black

Mother of two Bonnie Black was found dead inside her home in Arlington, Va., on April 17. The 42-year-old was found stabbed to death after her two young children were spotted wandering on the street. Black's estranged husband lives a few blocks away. Back in April, police said he is cooperating with the investigation and has not been detained or placed in police custody.

Palak Bhadreshkumar Patel

Police found Palak Bhadreshkumar Patel dead on April 12 in the kitchen of the Dunkin' Donuts in Hanover, Md., where she worked with her husband. The 21-year-old had been stabbed multiple times with a large kitchen knife. Anne Arundel County police quickly identified her husband, Bhadreshkumar Chetanbhai Patel, as the suspect. In late April, the FBI said he was last seen near Newark, New Jersey. Police said this week that they are continuing to look for the suspect.

Tamara Gliss

Just after sunset on Memorial Day, 31-year-old mother Tamara Gliss was fatally shot in the head outside her apartment building. Sources believe the shooting in D.C.'s Shaw neighborhood was gang-related. Police say someone on a dirt bike may have fired the deadly shot. Gliss' mother spoke at a candlelight vigil a few days after the shooting and urged anyone with information about her daughter's death to come forward. Police have made no arrests.
