The boyfriend of Morgan Freeman's granddaughter pleaded not guilty Tuesday to a second-degree murder charge in her stabbing death, and newly released documents show he ranted about Jesus Christ and the devil to officers after his arrest.

"I don't even know why I'm here right now," Lamar Davenport told two police officers at a Manhattan precinct stationhouse shortly after he was arrested Aug. 16 standing over Edena Hines' body, a knife still sticking out of her chest, according to prosecutors.

Twenty minutes later, while being driven to a hospital, the 30-year-old Davenport called Jesus Christ "savior" and the devil "evil" before telling the officers to "repent for your sins," the court papers show. He also asked the officers if they believed in Jesus and complained his handcuffs were too tight, according to court papers.

A lawyer representing Davenport didn't immediately respond to a message seeking comment. She told a judge Tuesday her client was set to undergo a psychiatric evaluation Thursday, the Daily News reported.

Hines, 33, is the step-granddaughter of the Oscar-winning actor, who has said through a publicist he thought of her as a granddaughter.

She was discovered on a street with at least 15 stab wounds to her chest and body.

After he was arrested, Davenport was taken to a hospital where he was given sedatives, according to the court documents. He then awoke screaming, "Why did this happen? No, no. Why God?" the court papers show.
