The charges were upgraded to murder Tuesday.

Edmund Silveira was medically cleared and released from the hospital. He was then arraigned as a fugitive from justice in Providence.

The judge ordered him held without bail, but did not allow the Taunton man to waive extradition at this time due to concerns by his attorney over competency.
