A 5-year-old girl who lost her mother in a suspicious fire two years ago was attacked with a stun gun by her father at their South End apartment, authorities said.

The girl suffered an injury to her abdomen from the gun, which is illegal to possess in New York. The incident took place Wednesday night when the father, 32-year-old Daniel J. Ulacco, threatened his live-in girlfriend with the weapon before turning it on his screaming daughter, according to police and court records

Ulacco, who told police he works as a bricklayer, was arrested after his girlfriend called 911. She told police Ulacco had been drinking before they argued. He was charged with felony counts of assault and weapons possession, and misdemeanor counts of menacing and endangering the welfare of a child.

Stun guns have grown more common in recent years and are often purchased from magazines, over the Internet or in states where they are not outlawed. The weapons are about the size of an automatic garage door opener and can carry a charge of up to 100,000 volts. They can cause burns and are used to hurt, stun or disable a person -- depending on how long they are applied to someone's skin or clothing, authorities said. More from the timesunion.com
