A judge has ruled that an unemployed doctor is competent to stand trial for murder in the killing of a Yale University physician he once worked with.

A prosecutor says Superior Court Judge Roland Fasano ruled Monday that Lishan Wang has been restored to competency. Wang is charged with shooting Vajinder (vah-JIN'-der) Toor to death last year outside Toor's home in Branford, Conn.

A judge ruled Wang incompetent to stand trial last September, but said he believed psychiatric treatment would restore Wang to competency. A psychiatrist testified in December that he believed Wang was competent, but defense lawyers challenged that opinion.

A message left for Wang's attorney was not immediately returned.

Workplace confrontations with Toor and others at Kingsbrook Jewish Medical Center in New York led to Wang's dismissal.
