Affidavit: Baby Dropped Into Lake

The mother of a missing 9-month-old baby girl told police that the child's father tied a sandbag to their daughter's lifeless body and dropped her into Lewisville Lake, according to a police affadavit released Monday.

Tamaira Creagh was arrested Monday on charges of tampering with evidence to hinder an investigation. Her boyfriend, 20-year-old Alandus Weaver, was arrested Saturday night on the same charges.

Police searched the water near the I-35 bridge for a second day on Monday for any evidence to link to the case, but have not yet called off the Amber Alert.

Creagh, 19, initially claimed a masked man broke into her apartment, tried to sexually assault her, then snatched her daughter Daisja Weaver last Tuesday.

But on Saturday, June 13, Creagh met with police and told a different story.

She said on Monday, June 9, her boyfriend picked her up from work alone. When she asked where Daisja was, he replied the child was at home by herself, and that he had given her a bath.

They returned to find the baby wrapped in a towel on the floor. Creagh said the Daisja was cold to the touch and didn't have a heartbeat.

The affadavit says Weaver performed CPR for 30 minutes, but became violent toward Creagh when she asked what happened to the baby. When Creagh tried to call 911, she said that Weaver stopped her, saying they had to "stick together."

The next day after work, she said he made Creagh drive with him to Lewisville Lake, where he stopped on a bridge, tied a sandbag to the baby's body and dropped it into the water.

Police initially waited more than 12 hours after Creagh first called them to declare an Amber Alert because they said her story details kept changing. They were skeptical of her kidnapping story because she did not have a good description of the kidnapper.

Creagh was being held in the Dallas County Jail.

In a statement sent to FOX 4 her attorney said, "In spite of her extensive cooperation with law enforcement and continued victimization by all involved, Mrs. Creagh has been unfairly subjected to criminal prosecution. While she remains anxious to cooperate and seek justice for her child, law enforcement personnel have erroneously made her a suspect as opposed to the victim and witness that she actually is."

Weaver remains in jail in lieau of a $100,000 bond and a hold from Richardson police on a no driver's license charge. His family members have previously said Weaver thinks Creagh is trying to blame him for whatever happened to their daughter.
