BUTLER TWP — A first-degree burn on a 1-year-old boy's arm led to charges against his mother.

District Judge Kevin O'Donnell issued an arrest warrant Wednesday for Amanda M. Cyphert, 32, on a felony count of child endangerment after Butler Township police accused Cyphert of failing to supervise her son, who suffered a first-degree burn on his left arm in early March.

Authorities report Cyphert told investigators she did not know how the boy was injured.

The police investigation began March 7 after a report through the ChildLine abuse hot line indicated the victim's apparent injury, according to charging documents.

The burn reportedly occurred at the defendant's Old Plank Estates apartment on or around March 1.

By the time of the ChildLine report, however, the toddler was already in the custody of Butler County Children and Youth Services.

Investigators said the agency removed the child on March 3 after police were called to Cyphert's home for a domestic dispute. Cyphert was later taken to Butler Memorial Hospital for an unspecified reason.

Responding officers described the defendant's apartment as being “in complete disarray” with clothing and belongings strewn on the floor.

Officers did not see the burn during their initial call to Cyphert's apartment, but at least one CYS representative saw the injury when the agency took the child into custody, according to court documents. However, police said they were not notified of the injury.

A pediatrician examined the toddler March 4, diagnosed the burn and prescribed treatment for the injury, police said.

Cyphert voluntarily went to the police station March 21 for an interview. She told investigators she was the sole caretaker for her son at the time of his injury. According to court documents, she admitted that she had been “abusing medications and was awake for three to five days.”

Authorities added that Cyphert acknowledged that she would leave her son unsupervised for periods of 10 minutes when she would go into the bathroom and close the door to smoke a cigarette.

“She stated she does not remember much during the time (her son) was burned, and agreed there was a lack of supervision,” investigators said in the affidavit.
