"He was my only child, a gift from heaven. All children are a gift from heaven but we had this bond where he could tell me anything and I could tell him anything."

Now that voice is silent for Linda Powell, and not a day goes by that she doesn't miss it, her son Mark.

Mark Gardner was murdered 15 years ago at 29th and Greenmount after a fun night out with family and friends.

"My heart is broken. I'm tired. I want the truth to come out. I don't like this don't tell don't snitch stuff, you can't do that."

Mark was shot four times in the back when he got out of the car. Powell believes he was targeted in a love triangle. He was married at the time with two young sons.

Attorney Pauline Mandel and her team are providing the support for Powell these days. She's the Director of Legal services for the Maryland Crime Victims' Resource Center, Inc.

They've been around for 25 years and right now Powell is among the 30 cold case homicide families in their support group.

"Every day is a problem. The milestones, that's when it really sets in with a lot of the victims."

Jeffery Gray, the investigator for the MCVRC works with the families in their journey for justice.

After more than 40 years in law enforcement in Prince Georges County, Gray knows any clue, no matter how small could make a difference in a case.

"In this case what we're hoping is even though it's 15 years ago, we're hoping that revisiting this incident that maybe someone will hear something think about something and come forward."

Linda Powell remains patient and prayed up, but her heart won't be whole until the person who took her son away from her is behind bars.

"I don't hate nobody. I just want the truth to come out and I want closure."
