A 46-year-old Lititz man has been charged with assaulting a woman over several days, including lighting her genital area on fire, police said.

Police charged Donald Dale Hackman Jr., of the first block of East Main Street in Lititz, with felony arson, aggravated assault, false imprisonment and misdemeanor simple assault.

The victim told police that Hackman, with whom she and her son had been staying with for about a month, assaulted her over the course of several days.

Hackman reportedly struck her repeatedly in the face and stomach with a closed fist and beat her several times with a belt, according to police.

It was during one of the assaults that Hackman lit her genital area on fire and yelled at her for screaming and crying. The victim told police that Hackman extinguished the flames.

The victim suffered second and third degree burns to her lower stomach, genital area and inner thighs, police said.

She was admitted to Heart of Lancaster Hospital and later the Lehigh Valley Hospital burn care unit where she is recovering, Lititz Borough detective sergeant John Schofield said.

"I've never dealt with injuries like that on any type of assault from a male toward a female victim," Schofield said.

"My heart went out to this woman," he said.

The victim also told police that Hackman locked her son inside a closet for approximately 20 minutes for "acting out" during the assault.

The victim's son is being cared for by a family member, Schofield said.

Schofield said Hackman did not resist arrest when police knocked on his door at 11:30 that night.

"I believe he knew why we were there," Schofield said.

Hackman was committed to Lancaster County prison in lieu of $500,000 bail.
