Taalibah Islam's family has never held a funeral for her.
She was 20 years old when she vanished in January 2006. Her sister Hadiyah Islam said family and friends searched for days, weeks, months and years.
"We had fliers, we made T-shirts," Hadiyah said. "They said, 'Taalibah, please come home.'"
But it has been nearly 11 years and Taalibah never came home. Hadiyah said the last person to see her was her boyfriend and father of her child, Christopher Revill.
The latest news from around North Texas.
According to police, he was also the last person to see Typhenie Johnson last Monday. He has since been arrested on a kidnapping charge and is being held in the Mansfield jail.
When asked if she believes Revill killed her sister, Hadiyah didn't hesitate to answer.
"Yes. He’s denying it, but I know. There’s no doubt. There’s no doubt in my mind. I know he did," Hadiyah said.
Fort Worth Police Sgt. Marcus Povero said Taalibah's case has remained open, but with Revill in custody in connection to the disappearance of Typhenie Johnson, they are looking even closer.
At the time, there was nothing linking Revill to Taalibah's disappearance, he said.
"Since what's happened, that investigation is going in a different direction," Sgt. Povero added.
Hadiyah said the most difficult part is never knowing what happened to her sister. They never had a body to bury, Hadiyah said, or a grave to visit.
Two families tied together through tragedy -- just praying for a different ending.
"Hopefully it will touch his heart to tell us where Taalibah is and tell us where Tyhpenie is," Hadiyah said. "I still think about my sister and I know they’re thinking about their sister."
Hadiyah said Revill dropped off the couple's 3-month-old baby to her family's home in 2006 and has not been seen or heard from since.
The child, who is 10 years old now, has been raised by his aunt.
Fort Worth police plan to resume searching for Typhenie Johnson on Monday.
