LOUISVILLE, Ky. (WDRB) -- There's a tree on West Oak Street in Louisville that serves as the center piece of a memorial for Louisville murder victim Jarvis Carson.

He was shot and killed in April 2013, when family members say he was walking home from work.

Whoever is responsible still walks free.

"I just want to find out what happened and be able to move on," said Shawn Carson, Jarvis Carson's mom.

Carson says she's trying to be patient. She knows answers will come with time.

"As hard as it is, it's even harder not knowing. I hope somebody sees this and knows we haven't given up getting justice for him," she told WDRB.

She says Jarvis left behind five children all under the age of 10.

"They'll ask how he's doing or if I know where he's at and it's hard to explain heaven to a child," said Shawn.

Jarvis Carson's sister, Ebony, said life without her older brother has been hard.

"He was killed on his daughter's birthday and she has to live with that. She has to live with that for the rest of her life and it's hard to explain to them that their father's never coming back," Ebony Carson said.

They described Jarvis as energetic with a huge smile.

"I think we're doing good holding our heads high because that's what he would have wanted: us to be happy," said Ebony.

Lt. Todd Kessinger with LMPD's Homicide Unit says over the last year, they've been able to gather a lot of information on the case.

"We're not at any point where we want to release information on what exactly we're looking for or who they are but the case is progressing. We've been working on it since the night that it happened," he said.

That includes possible suspects.

"There may be more than one person involved but we do have a general direction we're looking," said Lt. Kessinger.

While police work to find answers, Shawn Carson is trying to find a new normal for herself and her family.

"I never imagined my life would change so much, losing a child, because I always expected to go before them," said Shawn Carson.
