Ironside S07 E02 Murder by One

"«The chief of detectives!»"

The teenage son of a friend of Fran's appears to commit suicide, however the evidence seems to point in a number of different directions. Did he kill himself, or was it a murder made to look like suicide? Or, alternatively, was a suicide made to look like it could have been murder? The Chief has to unravel the story, but he has little real evidence to help him along.
