A 17-year-old was detained on multiple charges on Saturday after assaulting his mother and the family dog, according to the Aiken County Sheriff's Office.

John Schifferli, of St. Charles Way in Graniteville, was charged with two counts of third-degree assault and battery, animal cruelty and vandalism. He was placed in the Aiken County detention center, where he remained on Monday afternoon.

Schifferli's mother told deputies her son woke up “irate” about a crying baby, according to the sheriff's report. Schifferli began to curse and scream at her for no reason and asked for his mother's car keys, which she refused, according to the report.

At that point, Schifferli tried to take his mother's purse, police said. A struggle followed, during which Schifferli broke a computer desk in the home and assaulted his mother, causing scratches to her left hand, according to the report.

Once his mother got her purse away from him, Schifferli then grabbed a hammer and tried to hit a 22-year-old male victim with it, the report stated. The male victim was able to wrestle the hammer away from Schifferli, at which point Schifferli reportedly began “assaulting” him.

The report did not indicate a relationship of the 22-year-old to Schifferli and his mother.

After assaulting the male victim, Schifferli began punching the family dog in the head repeatedly and then fled the scene, according to the report.

An officer spoke with Schifferli on the phone and convinced him to return home.
