An Indiana teenager who pleaded guilty to murder has broken down while watching video of himself telling police how he strangled his 10-year-old brother.

Ohio Circuit Court Judge James D. Humphrey recessed court twice for a total of nearly an hour Thursday morning as 18-year-old Andrew Conley tried to control his emotions.

Defense attorney Gary Sorge said Conley wanted to be excused from the courtroom because he couldn't "bear to hear any more." Humphrey denied the request and said it was important that Conley be present to exercise his rights.

Conley pleaded guilty Monday as his trial was about to begin in the Nov. 28 murder of his brother, Conner Conley, at their home in the Ohio River town of Rising Sun. He could face 45 years to life in prison.
