“To know that your daughter, somebody that you birthed, is not here, that’s a hurtful feeling,” said the 18-year-old's mother, Makesia Sampson.
On Sept. 20, Phoenix police responded to an unknown call at an apartment complex near 35th and Grand avenues. Apartment management told officers they were in the process of evicting Mathis for not paying rent when they noticed a strong smell coming from her door.
When officers went inside the apartment, they found two plastic bags containing pillows with large amounts of blood. Officers also found several cleaning products in plain view and an inflatable chair in the living room with bloodstains.
Once officers went to the bedroom, they saw several burnt incense in the air vents. One side of the mattress had blood that appeared to be spray-painted with black paint. Officers also found blood on the carpets and walls. Mathis' body has not been found.
At the time of the investigation, police say Mathis had not been contacted for about three weeks. Police added Mathis' phone was turned off and her car was not at the apartment complex. Staff there told officers that Mathis was the only person who lived there but was seen with Jones several times. During the investigation, police say they found a white tank top, men's underwear and a wave cap with apparent bloodstains.
Sampson says Jones used to be a family friend. She denies reports she was romantically involved with him, but says she was concerned about the suspect’s relationship with her teen daughter.
“She was hiding it, and I knew it,” said Sampson. “I’m not about to go for that.”
Sampson says she last heard from Mathis in July. She wants Jones to pay for what he did.
“She’s not going to get to see birthdays and Christmases,” Sampson said. “She won’t get none of that. She’s gone. Why? For nothing.”
Police say Jones has a criminal history and was involved in several domestic violence assault incidents with Mathis between May and July 2019. During one of the incidents, Jones hit Mathis in the face several times, causing injuries.
On Sept. 16, Jones was spotted at a Walmart near 35th and Southern avenues, buying a shovel and chlorine. He was also seen leaving the parking lot in Mathis' vehicle. On Nov. 26, police arrested Jones at an apartment complex near 27th Avenue and Bethany Home Road.
Jones is in jail on charges of second-degree murder. Police also booked him on suspicion of abandonment or concealment of a body and misconduct involving weapons.
