A Centre County man convicted of beating a Penn State student to death more than two years ago is asking for a new trial.

Andrew Rogers was previously convicted of third-degree murder in the beating death of Young Cheol Park.

On Thursday, Rogers' attorney asked a just to consider a retrial and raised the issue of if police and prosecutors withheld information that could have changed the outcome of the trial.

Rogers has always maintained that he beat Park to death in self-defense. He said another man he called "Sweet" was also at the State College home when Park was killed, and Rogers said he was fighting both Sweet and Park. Police said Sweet was never found.

Several months after Rogers was convicted, evidence surfaced that Park's watch was stolen and the man who ended up with it said he obtained it from a man called "B," who in some ways matches Rogers' description of Sweet.

Rogers' attorney said he wants a new trial and questioned the prosecution's ethics in the case, claiming the evidence wasn't turned over in a timely manner.

The prosecution contends the stolen watch had nothing to do with Rogers being found guilty of murder.
