A heartbreaking turn in the search for Shavon Randle, the 13-year-old Lancaster girl who was the subject of an Amber Alert for the past couple of days.

Her body was discovered inside an Oak Cliff home late Saturday night.

According to the FBI, Randle, and an adult male were both discovered deceased inside the home in the 2200 block of Kiest Avenue.

"We have positively identified the young female is Shavon Randle. We have notified the family of this information and we’re in the process of continuing our investigation.” said Eric K. Jackson / FBI Special Agent in Charge.

The FBI received a tip which led investigators to the home at around 10:30 p.m. Saturday. There was no other information immediately available as to why investigators were targeting the house.

After Friday's FBI plea for information related to Shavon Randle's disappearance, 24-year-old suspect Devontae Owens was arrest by the Lancaster Police Department and the FBI earlier Saturday. Owens is now being held on aggravated kidnapping charges in the Dallas County Jail.

An additional suspect, 30-year-old Laquon Wilkerson, previously not named, was identified and also arrested by the FBI and the Lancaster Police Department in connection with the case today.

Officials located 25-year-old LaPorschya Polley and 26-year-old Darius Fields, two of the four persons of interest who they have named in connection with the case on Friday. They were being questioned and remain in custody.

Authorities are still searching for 19-year-old Michael Titus.

“They are individuals that we believe may have information related to the kidnapping of Shavon,” said Eric Jackson, FBI special agent in charge, during a press conference Friday at Lancaster Police Department.

In an interview, Titus’s mother said she does not believe he would be involved in the kidnapping of Shavon.

She says on Thursday, her son's girlfriend sent her text messages that her son wrote on Monday night. In them, he wrote that someone was coming to a house to buy marijuana. He was running late, so he told his female cousin to open the door for the customer.

“My female cousin open the door and he rob her and took her gun,” the text said.

He wrote that now his cousin believes that he had something to do with the robbery. “So if these (n-word) kill me, … screenshot this and show the police,” the text said.

Titus’ mother said she immediately contacted the police and gave them the text messages. On Friday, detectives were at a relative’s house interviewing her and other family members.

“I'm not saying my child is perfect by far, but what I do know that he would not be responsible for no kidnapping of another child,” she said. “I'm worried not only for this baby, but for my child.”

Titus’ mother asked WFAA to conceal her identity because she fears for her family’s safety. She said she had not heard from her son since Tuesday, which is very unusual since she typically speaks to him almost daily.

Through tears, she said she was desperate for answers about the whereabouts of her son and Shavon.

“I want the parents of this 13-year-old to have their baby safe in that house,” she said. “I don’t care about what was going on. All I care about is my child saying that his life was in danger and he’s going to be killed behind this.”

Titus’ mother said she did not know Polley. She said Owens is the father of her two nephews. Her son, she says, knows Fields through Owens.

“He knows them as almost like family,” she said.
