More details have emerged in court documents about the murder of a 10-year-old Cecil County girl, whose alleged killer was ordered to remain in jail without bail on Friday morning.

Richard Eugene Madden Jr. allegedly raped and killed Kami Ring before leaving her body in the field behind the Port Deposit house where she was staying, according to a statement of charges.

Kami's body was found Monday. She was partially nude, with signs of a cutting injury to the neck and injuries indicating she had been raped, as well as having been struck in the head, the charging documents state.

Madden, 29, who had just been released from prison in February after serving time for theft, was charged Thursday with first-degree and second-degree murder, as well as rape and assault.

Madden was already in police custody when the murder charges were filed. He had been charged with drug offenses on Monday, during the time Maryland State Police were investigating the girl's disappearance, and had not posted bail in the drug case.

Kami was reported missing Sunday night from the Waibel Road home where Madden lives along with a couple the girl called her "grandparents" and who are identified in the charging documents as Walter Clark and Cynthia Clark. In addition, Madden appears to have considered the girl his "niece," even though State Police have said there was not a biological relationship between Kami and anyone living in the Waibel Road home.

In the news release announcing Madden's arrest on Thursday, State Police identified the Clark couple as "the parents of Madden."

The charging documents also state: "Ring is the friend of the daughter of the family."

Cecil County State's Attorney Edward Rollins declined to comment on the relationships, or any other aspects of the case, Friday morning. He said it was his office's policy not to comment on such matters.

Madden consented to a DNA test, which positively linked him to biological evidence on Kami's body, according to the charging documents.

A shoestring was found on the girl's body as well, and police found gray tennis shoes belonging to Madden with missing shoestrings, the charging documents state.

Madden also had scratch marks on his chest he could not explain, the charging documents state.

Walter Clark, the man Kami knew as her "grandfather," told police Madden's shoes normally have shoelaces, the charging documents continue.

Clark also said he woke up at 7 a.m. on Monday, the day Kami was reported missing, and saw Madden doing laundry, which seemed "completely out of character," according to the statement of charges.

Madden told Clark he needed to wash his work clothes. He had just returned from a shift at Denny's Restaurant, where Cynthia Clark had picked him up after she presumed Kami had gone to bed, the statement of charges continues.

But Madden also seemed to be "not acting himself" and "troubled" that morning, Walter Clark told police.

Madden told investigators he returned from work, took a shower and slept on the living room couch instead of in his bedroom, according to the charging documents.

He told investigators he awoke at 9 a.m. Monday and started making breakfast for Kami, then called his cousin who arrived and found Kami missing, according to the charging documents.

In a post on his Facebook page, dated Monday, Madden wrote: "right now i am going out of my [expletive] head.........my neice kami want missing some time in the night or morning... so pleas if i have seen or heard anything please let me know ASAP."

One neighbor told investigators that the search should include the field across from the home, but when she began walking over to it, Madden grabbed her arm and said, "Those babies would not be walking over there near those briars" and suggested the search should instead focus on the area around power lines in the opposite direction, according to the charging documents.
