GREENSBORO, N.C. -- In October 2013, 72-year-old Mildred Martin, of Greensboro, was found murdered in her home on Hyalan Court in a quiet neighborhood off Alamance Church Road.
Martin was known by all as "Miss Mickey" or "Aunt Mickey" by her nieces and nephews.
Martin was a foster parent for more than two decades, an active member of her church, a spiritual woman and loved by many.
"It doesn't make sense. I don't know that it will ever make sense other than the fact that there are just mean, vile people in the world," said Davetta Dunlap, Martin's niece.
On the third anniversary of her murder, the family gathered in one of Martin's five sister's homes.
"Three years is a long time for us to go through this as a family and as you see we have a lot of people here supporting her, family supporting her and the police department, I know they are doing what they can," said Gregory Carter, Martin's nephew.
Carter says he's not content with where things stand at this stage in the investigation. "Maybe we need to go to the next level, that's something to really think about," he said.
Martin was stabbed to death and her car had been abandoned somewhere else. It all happened in the early evening, in broad daylight. Both police and the family says Martin was very security conscious and always locked her doors and had an alarm system for her home.
"Everyone in the neighborhood knows that she was alone, everyone knows that she was the only one that drove her car," Carter said
To this day, the killer is still out there, and that's something the family can't bear.
"This is a major travesty that has gone on with our family and we need help," said Cater.
For more than a year the family waited for the state crime lab to process DNA. Det. Will Morton says several samples came back just last month but were inconclusive.
"We just don't lose heart and I know it's hard for my mom and her sisters and for the cousins because we just miss Aunt Mickey's presence every day," Dunlap said.
Investigators say the case is far from cold. They do have some persons of interest, but need more evidence to connect them to the crime. They are also still reaching out to Martin's former foster children to get background information on potential suspects.
The family says while they are heartbroken and frustrated they won't give up.
"I think we will be committed to seeing it get solved whatever that takes, I don't know what that will take -- just persistence and prayer," Dunlap said.
