Almost four years after her son, a Marine, was gunned down, a Massachusetts mother is pleading for justice.
"I believe that people out there know who did this and it's time to come forward," said Anita Clark, the mother of Malden murder victim Shawn Clark.
This Veterans Day, she is begging for information in the unsolved murder.

"He did tours in Iraq and the Middle East and it's just awful that he had to come home and succumb to the violence here," she said.
Anita Clark's only son was killed in January 2013 just outside the skate shop he owned on Main Street in Malden.
"As far as I know it was a robbery, they pulled the gun out, there was a scuffle, confrontation, and they shot him to death," Clark said.
Take a close look at this previously released surveillance video – two suspects were captured on camera inside the shop, one pulling a gun on Shawn, with his face partially obscured.
But nearly four years later, no one has been charged in the murder.
Clark says the Middlesex District Attorney's office is "reinvestigating" the case and now has it as one of two featured unsolved homicide cases on its website.
"We currently have new detectives on the case and a new chief investigating officer, a new prosecutor," said Anita. "They are looking at all the previous leads that came in and following up on that."
Clark says once again this Veterans Day, she will go to her son's grave and tell him they haven't yet caught his murderers.
"I went to see him yesterday and it was very hurtful," she said through tears.
But she hopes that will soon change.
"That would mean the world to me and my family," Clark said.
