An Ohio mother last week pleaded not guilty by reason of insanity to allegations that she murdered her 5-year-old daughter in January, PEOPLE confirms.
MingMing Chen, 29, is scheduled to be tried on charges of murder, tampering with evidence, obstructing justice, gross abuse of a corpse and two counts of endangering children in connection with the death of her daughter, Ashley Zhao, according to the court clerk’s office in Stark County, Ohio.
The girl’s body was found hidden in the family’s Chinese restaurant one day after her parents reported her missing.
Authorities allege Chen, of Canton, Ohio, hit Ashley early on Jan. 9, causing fatal injuries before her parents concealed her body.
Chen entered her plea during a court hearing on Thursday. Her attorney did not immediately respond to a request for comment.
Liang Zhao, the girl’s father, pleaded guilty in the case on Sept. 11. He admitted to gross abuse of a corpse, obstructing justice, tampering with evidence and two counts of endangering children, the prosecutor’s office previously confirmed to PEOPLE.
A murder charge against him was dropped.
Zhao agreed to testify against his wife under a plea deal and will be sentenced after her trial has concluded, the court clerk’s office confirms to PEOPLE. As part of the plea agreement, he will be sentenced to 12 years in prison, according to the Akron Beacon Journal.
