According to People magazine, 35-year-old Sini Matthews was arrested Thursday and charged with abandoning or endangering a child. Authorities are alleging she left Sherin at their home unaccompanied for an hour and a half the night before Oct. 7, when she was first reported missing.

Her body would not be recovered until Oct. 22.

Sini Mathews is being held on $250,000 bail. According to the arrest affidavit, Sherin was left by herself because Sini and her husband took their biological daughter out to dinner that night. Police concluded this placed Sherin in “imminent danger of death, bodily injury, or physical or mental impairment.”

Her husband, Wesley Mathews, is charged with felony injury to a child after it was revealed Sherin choked on milk he was trying to get her to drink, instead of vanishing from outside their home like he initially told police.

It was Wesley who told police they went out to dinner the night before Sherin was reported missing. They checked with the restaurant to confirm only one of the Mathews’ children was with them at dinner, and found a receipt proving the family was there that night.

The Dallas County Medical Examiner still has not determined the cause of Sherin’s death.
