An Edmonton woman accused of drowning her son has been found fit to stand trial but her lawyer is seeking a second opinon because he believes she could be found not criminally responsible.

Nerlin Sarmiento, 32, is charged with first-degree murder in the death of her seven-year-old son Omar Jajoy.

Sarmiento has been in Alberta Hospital for a court-ordered psychiatric assessment since February. The result was discussed during a court appearance in Edmonton on Friday.

Sarmiento will now return to the psychiatric facility for an assessment by a different psychiatrist.

If the same conclusion is reached, defence lawyer Peter Royal said "then we'll have to sit down and figure out what to do."

Sarmiento appeared in court with leg shackles, sweat pants and a black hoodie.

She appeared more alert than in previous court appearances, but did not acknowledge her family who sat in the gallery.

The case will be back in court on May 10.
