RICHARDSON, Texas -- An arrest warrant obtained by WFAA in Dallas Tuesday details the conflicting story that led to the re-arrest of Sherin Mathews' father, Wesley Mathews.

The 3-year-old went missing earlier this month. The coroner confirmed Tuesday that a body found over the weekend was Sherin.

The warrant states that Wesley Mathews told police his daughter choked on milk in the early morning hours of Oct. 7 and "believed she had died."

He alleges that he had been trying to get her to drink her milk in the garage around 3 a.m. He said he "physically assisted" Sherin in drinking her milk when she wouldn't listen to him, according to the warrant.

"She was coughing and her breathing slowed," the warrant reads. "Eventually, Wesley Mathews no longer felt a pulse on the child and believed she had died."

He then admitted to police that he removed the body from the home, the warrant reads.

In his initial interview with police in the days after Sherin's disappearance, Wesley Mathews had said he put Sherin outside as punishment for not drinking her milk. He was arrested then and charged with felony endangerment to a child and was placed on electronic ankle monitoring. He also surrendered his passport as a condition of making bond on Oct. 9.

He was re-arrested Monday for felony injury to a child after providing investigators at the Richardson Police Department with the conflicting story.

"When they came in, they provided us with some information that was contrary to what we had previously been told regarding her [Sherin Mathews] disappearance," said Kevin Perlich, Richardson PD spokesperson.

His bond has been set at $1 million and he was booked into the Richardson City Jail.

"It is possible that he could bond out again," Perlich said.

When asked Monday about the milk story Mathews originally told police, Perlich wouldn't provide specifics because it was an ongoing investigation. All he could say was that "it was not what he told us originally."

A medical examiner confirmed Tuesday that a child's body found in a culvert Sunday is Sherin.

The FBI seized dozens of items from the family's home and their vehicles between Oct. 8 and 12, including a washer and dryer, electronics and DNA swabs.
