The police on Monday arrested the father of missing three-year-old Dallas girl Sherin Mathews after he gave new answers to investigators’ questions about her disappearance, AP reported.

Sherin Mathews has been missing since October 7, when her father Wesley Mathews made her stand in the backyard of their house at 3 am as a punishment for not drinking her milk. He went to check on her 15 minutes later and found she was gone, and reported her missing around five hours later. He was arrested for suspected child endangerment and later released on a bond.

On Sunday, authorities said they had found the body of a three-year-old, who they believe could be Sherin. The body was in a culvert about a kilometre from the Mathews’ home. Richardson Police Sergeant Kevin Perlich said the body was “most likely” Sherin Mathews’ but the medical examiner has not yet confirmed it.

On Monday, the police arrested Wesley Mathews again for giving new answers, and charged him with injury to a child, a crime punishable by up to life imprisonment. Perlich, however, did not say how Mathews’ statements were different from his previous ones about the disappearance of his adopted daughter, The Washington Post reported.

Sherin was born in India and adopted by Mathews’ family. She suffered from malnourishment before arriving in the United States and was on a special diet.
