A 14-year-old boy accused of raping and murdering his 83-year-old neighbor in Baltimore was ordered held without bail on Monday.

Tyrone Harvin – the youngest suspect charged with murder in Charm City this year – was arrested Friday and charged as an adult in last month’s attack on Dorothy Mae Neal, who was found beaten and sexually assaulted in her West Baltimore apartment on Aug. 29. The elderly woman, who lived alone, died from her injuries at a hospital the following day, the Baltimore Sun reports.

Harvin may have been doing a chore for Neal when he attacked her and evidence in the woman’s apartment links him to the crime, according to investigators, who declined to elaborate.

“Almost 70 years separate our victim and suspect,” police spokesman TJ Smith told reporters on Friday. “It’s sad all the way around. There’s some systematic failure in the 14-year-old’s life to allow us to be here talking about him being accused of murder and rape. It’s just a very tragic situation all the way around.”

In Maryland, murder, rape and major sex offenses are among the crimes that suspects ages 14 and older are automatically charged as adults. Harvin is the youngest suspect charged with murder in by Baltimore this year and possibly several years, Smith said.

Neal, who died of blunt force trauma, was found unresponsive at her apartment after a neighbor called police and said she hadn’t been seen for several days. Harvin allegedly “beat her to death,” Smith said, adding an autopsy revealed that Neal had also been sexually assaulted.

Investigators were still trying to determine a motive for the heinous crime. No signs of forced entry were found, police have said.

Harvin’s mother, meanwhile, said police arrested the wrong suspect, claiming her son was not involved in the attack.

“He wouldn’t do that to an elderly … no, he would not,” the woman who refused to identify herself told WBFF. “I’m just hurting. I’m torn on the inside.”

The woman said she spoke to her son from jail late Friday.

“He’s saying, ‘Mommy, I didn’t do it,’” the woman continued. “He said he didn’t do it and I believe what my son [said].”

Neil, according to court documents revealed Monday, had multiple fractures to her face, as well as tears and lacerations to her anus and vagina. Harvin’s fingerprints were also found on a condom wrapper found inside Neal’s apartment, the local Fox affiliate reported.

Harvin initially told cops he didn’t know Neal and insisted he had never been to her apartment, but he later admitted helping her take out some trash. Harvin said he returned to the woman’s apartment to talk to her about church, according to the station.

Neal’s relatives could not be reached for comment, according to the Baltimore Sun, but the neighbor who called police said she was relieved that an arrest had been made.

“I’m glad they caught him,” the woman told the newspaper. “She’s in a better place.”
