RISING SUN, IN (WAVE) - An Indiana teen who plead guilty to killing his ten year old brother is expected to be sentenced Monday.
Last week, Andrew Conley admitted, just as trial proceedings were to begin, to strangling his 10-year-old brother Conner. It happened in Rising Sun, Indiana in November 2009.
The 18-year-old says he modeled the murder of his brother after the TV serial killer "Dexter".
Conley's mother testified in court on Friday and said she had no idea what had happened. She said Andrew actually ate popcorn and joked with her the morning after the attack.
Prosecutors are seeking life in prison against Conley.
