DALLAS — The father of an eight-month-old girl who has been missing since late Tuesday night has been jailed and is considered a suspect in her disappearance, police said Sunday.

Alandus Weaver, 20, was booked into the Dallas County Jail at 10:55 p.m. Saturday and charged with tampering with physical evidence to impair an investigation. He is also being held on an outstanding warrant out of Richardson.

"He looked me straight in the eye and said, 'Dad, I do not know where this kid's at,'" said Alandus Weaver Sr., the suspect's father.

Dallas police spokesman Kevin Janse confirmed to News 8 that Weaver is a suspect in Daisja Weaver's disappearance.

"[The mom] recanted her story about the kidnapping and we know that didn't take place," Janse said.

Daisja was reported missing by her parents at 11:30 p.m. on June 9. Daisja's mother, 19-year-old Tamaira Creagh, told police that the infant was snatched by an intruder who had tried to assault her in the family's far North Dallas apartment, but police said the child's parents offered conflicting statements about what had happened.

"Although uncorroborated information, she did give us some information that led us to believe that the child had been harmed by the father," Janse said.

Alandus Weaver was jailed Saturday night.

This led an extensive search for evidence of Lake Lewisville Sunday afternoon, but police found nothing. Weaver's father challenges Creagh's story. He said he believes his granddaughter is still alive.

"Get this baby home," he said. "We want this kid back home. We really do."

Weaver is being held on a bond of $100,000.

Daisja, the subject of a national Amber Alert, remained missing Sunday morning. The $10,000 reward offered by Schepps Dairy for information leading to the arrest and conviction of anyone responsible for her disappearance has been raised to $15,000.
