Mantas still could face criminal charges if he is determined competent to stand trial.

Prosecutors had hoped anti-psychotic drugs would make Mantas mentally stable enough to understand the charges against him.

However, an investigation by the county counsel's office and the public guardian's office determined that he is too mentally ill to leave the hospital.

The public guardian's office now will determine whether Mantas qualifies for conservatorship, under which a person or organization would oversee his care and finances.

A hearing on the conservatorship will be held June 13 in Contra Costa County.
