She will then be admitted to the Bellefaire residential treatment center, a counseling center near her family, for six months, after which she will be released to her family to be supervised for a period of two years, Mr. Friedman said.

After initially being charged with aggravated murder, a charge that could have put her in prison for life were she tried as an adult, Bresha can now have her complete record sealed in three years and purged in five years, Mr. Friedman said, emphasizing that she would likely reach adulthood without a lasting record of the case.

“Bresha is incredibly relieved and feeling optimistic about her life for the first time,” Mr. Friedman said Tuesday. “It was nice to see her genuinely smile yesterday. This young girl will now have a very bright future.”

Several of Mr. Meadows’s relatives, including his sister, had accused his daughter of mercilessly killing a sleeping man who had not been abusive in years. But other members of the family, including Bresha’s mother, Brandi, described a pattern of verbal and physical abuse that never let up for long.
