An Indiana teenager accused of strangling his 10-year-old brother and dumping his body in a park has pleaded not guilty to murder.

Seventeen-year-old Andrew Conley showed no emotion during Friday's court appearance in Ohio Circuit Court in Rising Sun, the teen's hometown along the Ohio River about 90 miles southeast of Indianapolis.

His parents were at a viewing for his brother Conner Conley's body and did not attend the hearing.

Prosecutors say Conley confessed to police that he intentionally strangled his brother while they were wrestling at the family home on Sunday. They say Andrew Conley told investigators he had dreamed of killing someone since he was in eighth grade.

If convicted of murder, Conley could be sentenced to up to 65 years in prison.
