An Indiana judge has ordered a 22-year-old man remain in jail without bond on charges that he raped and killed a 14-month-old toddler little girl who he kidnapped from her father's home.

Kyle Parker, 22, pleaded not guilty to charges of murder, kidnapping, rape, child molesting, aggravated battery, strangulation, obstruction of justice and failure to report a dead body in Shaylyn Ammerman's death via video link from the Owen County jail for his initial court hearing Monday afternoon.

Owen Circuit Judge Lori Thatcher Quillen appointed attorney Jacob Fish as Parker's public defender, The Associated Press reported.

Court documents say Parker was drinking whiskey with Shaylyn's uncle and took the girl from the Spencer home where her father, uncle and grandmother lived after family members had fallen asleep.

Charging documents say investigators questioned Parker after Shaylyn was reported missing Wednesday morning from the Spencer home where her father, uncle and grandmother lived.

The documents say Parker first denied involvement, but later directed police to the rural wooded location where her body was found Thursday night near the White River. His trial is currently set for August 10.

An autopsy found Shaylyn suffered severe sexual trauma and died from asphyxiation.

Forensic pathologist Dr. Donna Stewart, who specializes in pediatric autopsies involving sexual battery and molestation, said that the toddler's sexual assault was the 'worst case of sexual trauma she had seen in her career,' the affidavit said according to the Indianapolis Star.

She said Shaylyn was beaten, raped, smothered and strangled.

Angry: Shaylyn's uncle, Adam Ammerman (pictured), was friends with Parker. He told reporters that he hoped the man would 'burn in Hell'

Shaylyn's grandmother, Tamera Morgan (pictured, with Shaylyn), says that Parker had visited the home around a dozen times, and that he 'talked kindly' and played with the toddler

Parker confessed to his stepfather that he raped and then smothered the toddler, before he poured bleach on both of their bodies in an attempt to destroy DNA, WLFI reported. He also reportedly told his stepfather that he burned Shaylyn's clothing and pacifier.

In addition, Parker reportedly told his stepfather that he acted alone in the horrific crime, but planned to try and confuse investigators by accusing one of her family members.

Friends of Parker told police that he was attracted to young girls and that he liked pornographic videos with sadistic and masochistic themes, WFTS reported

However, he reportedly denied those claims when he was interviewed by authorities.

Parker, who hasn't had a job since last year when he worked at a nursing and rehab center, was a 'family acquaintance' who visited the home a dozen times and used to play with the child.

Shaylyn's uncle, Adam, said: 'He knew Shaylyn, he's played with her, he's taken care of her. He rocked her to sleep.'

He added: 'I knew Kyle through a friend of a friend and he was supposed to be one good friend, and then he turned around and does this to our family, and all I can say right now is I hope he burns in Hell.'

Parker was at the girl's father's home on Tuesday evening, Justin Ammerman told ABC 6.

The girl's father and grandmother, Justin Ammerman and Tamera Morgan, were the last people known to have seen her late Tuesday when she slept in her cot.

The child, who had earlier been put to bed by her father, Justin Ammerman, had disappeared by the following morning.

She had been staying at her father's home under a joint custody arrangement with the girl's mother.

More than 100 people from several police departments and other agencies searched two days for Shaylyn until her body was found.

Owen County Sheriff Leonard Sam Hobbs said Friday that there are still many unanswered questions in the case.

The girl's father, who was subject to a police polygraph test earlier on Thursday, has denied claims he was having a party on the night of his daughter's apparent abduction.

But family members told the Herald-Times that Shaylyn's father, uncle, grandfather and a family friend - believed to be Parker - were up late drinking whiskey and watching television.

The gathering wound down at about 2am when the friend is said to have left the family home.

Justin Ammerman said the family went into 'panic mode' when they realized Shaylyn was missing the next morning.

Shaylyn's mother, Jessica Stewart, confirmed her daughter had been found dead in a heartbreaking Facebook post on Thursday evening.

'My babygirl Shaylyn is gone. They found her body tonight,' she wrote.

Stewart and Justin Ammerson shared custody of Shaylyn, who was spending the week with her father when she disappeared.

The child's mother earlier said her former partner knew more than he was letting on, saying she believed her daughter had been abducted.

'I don't know if he had anything to do with it but I think he knows something at the very least that he is afraid to say,' she told WTHR.

However Tamera Morgan, Shaylyn's grandmother, defended her son.

'He has nothing to do with her disappearance other than he is the father. He put her to sleep like anyone else would,' she said.

Anyone with information is urged to call Indiana State Police on (812) 332-4411.

Indiana State Police say they don’t anticipate any additional arrests, but the investigation is still ongoing.
