NEWTON COUNTY, Texas — 12News reporter Tyler Seggerman sat down with Evelyn Clark, 62, about two months ago where she spoke about the murder of her son Dexter Diggles, 29.
Sadly, Clark died last week after battling cancer.
Her family agreed to let us share her interview, in the hopes that Diggles' killer will finally be found.
Clark says "It's not a good feeling, I wouldn't wish this on no mother."
For Clark, the death of her child consumed her with heartbreak and fear.
"Dexter was very friendly, he had a lot of friends," says Clark. "If he had enemies I didn't know anything about it."
On November 15, 2015, Clark was cooking at her home in Call, TX.
Shortly after 3 p.m. that evening, she got a knock on her door that would change her life.
"When she knocked on the door with her mama, they both told me that 'ma'am i'm sorry, but your son out here dead,'" says Clark. "I said who, where?...That's when they showed me Dexter and that's when I called 911."
Clark found her son lying on the ground in her front yard, near his car
"It haunts me, I still stay up at night," says Clark. "I stay up every night, I can't sleep at night, I haven't slept since Dexter died."
Former Newton County Sheriff Eddie Shannon led the investigation, but ultimately decided to close the case.
Then, Sheriff Billy Rowles stepped in.
"He said 'when I become sheriff, I'll make it my priority,'" says Clark. "He opened the case."
"I had dealings with this lady when I was running for sheriff," says Sheriff Rowles. "She made several contacts with me to see, asking once we got into office if we can get involved, and of course we did."
Sheriff Rowles opened the Diggles case shortly after taking office in 2017.
He tells us Diggles died from a single gunshot wound to the head.
"She goes down to look at him and low and behold, he's got a bullet hole in his head," Sheriff Rowles. "It went from one side to the other."
In the summer of 2017, the Newton County Sheriff's Office had a person of interest.
That fell through and now deputies are back to square one.
Sheriff Rowles says "As we are right now, we do not have a solid suspect in this case."
Clark tells us Diggles worked in construction and just arrived home from work on Saturday, November 14, 2015.
Clark left to go visit someone in the hospital that night, not knowing it would be the last time she would see her son.
"I took him to work Saturday morning and picked him up Saturday evening, brought him home and I said 'baby, I'm fixing to go see my pastor in the hospital,'" says Clark. "He said 'OK, mama'..I left and I came home at 11:00 that night."
Sheriff Rowles believes Diggles was shot and killed sometime Saturday night, but his body wasn't discovered until Sunday evening.
Rowles says "His car was there, but he was lying on the opposite side of the car from where she pulled in and didn't see Dexter lying there."
Clark feels her son wasn't killed outside her home, but dropped off.
"You know how you just lay a baby down, that's how Dexter was laying there, says Clark. "His clothes weren't disturbed or nothing."
The person who killed Diggles is still out there.
"Even though the police department tells me I'm ok, but i don't feel safe, says Clark. "I've put a fence around my house, I've put more security lights on and I have an alarm system."
She adds "I'm not going to feel safe until they find the person that killed my child."
Sheriff Rowles says he won't rest until the person responsible for Diggles' death is found.
"I would love to look the camera in the eye and say there is somebody out there that knows what happened," says Sheriff Rowles. "I would give anything in the world, for the family, to be able to solve this."
"I'm not mad at the person, I forgive that person. i just want the person to come forward and say 'i did it,'" says Clark. "I want to know why...that's all I want is justice, that's all I want."
Clark recently began her second battle with colon cancer after being in remission for 25 years.
She was working on a book called the "Silent Cry of a Mother."
Clark's funeral service is scheduled for Saturday, April 27 at 11 a.m. inside the Springhill Missionary Baptist Church in Kirbyville.
Although she will not be able to see justice served, Sheriff Rowles told 12News Monday that they have uncovered new details in her son's case.
