Sky McDonough a person of interest in Leanna Walker's death

MILFORD — Sky McDonough is being regarded as a person of interest in the death of girlfriend Leanna Walker as he remains in the Pike County Correctional Facility on unrelated charges.
The Pike County District Attorney’s office has since May 20 been treating the case as a criminal homicide investigation. No arrests have yet been made. The case is still under police investigation.
The remains of a body found on the grounds of Snyder Llama Farm in Milford were identified as Leanna Walker, the 17-year-old who’d been missing since leaving her Sunrise Lakes home on April 18.
The community organized a massive search effort to find the girl, including a Facebook search and help from NBC News' Missing in America.
Authorities continue to work to understand what led to the girl's brutal killing. Leanna's mother had ordered McDonough, 24, to leave their house after discovering Leanna was hiding him in her bedroom at night. Leanna left the house with McDonough and was not seen alive by her family again.
Leanna's disappearance greatly worried those who knew her well. Her friends said they’d seen signs of violence from McDonough. He threw shovel at her, they said, and made vile threats about what he would do to her if she ever were to leave him. Some friends say he was under psychiatric care.
McDonough’s Facebook page, which is still up, includes postings about Rastafarianism and many photos of him with Leanna. It lists his home as Franklin, N.H. Some who have posted on the site ask if they should keep his mail since it’s still going to their address.
The last photo McDonough posted was on the day of Leanna's disappearance, in which he is shown hugging Leanna from behind.
Leanna’s friend Halley Deskin said that although Leanna was very kind and caring, she could also be tough, so she wasn’t too worried when at first Leanna wasn't around. She thought she could take care of herself.
Both Halley and Leanna’s sister Diana Bostedo said people, including McDonough, sometimes took advantage of Leanna's kind nature.
Halley said McDonough was interested in Rastafarianism and called Leanna "his wife," and threatened to kill her if she ever left him. The couple was forever breaking up and reuniting, Halley said.
