Fresno police say four people, including two children are dead, after an apparent murder-suicide early Sunday.

The Fresno Bee reports that when police were called to investigate a disturbance at an apartment around 6:44 a.m., they found a man outside the apartment suffering from a stab wound.

Capt. Dennis Bridges told the newspaper that officers then heard a single gunshot. When they went inside the apartment they found a woman believed to be in her 20s with a self-inflicted gunshot wound and a man in his 20s or 30s dead of a gunshot wound.

Two children -- an 18-month-old and a 3-year-old -- also died from gunshot wounds.

The man suffering from the stab wound was taken to a local hospital, where he is reported to be in critical condition.

Police did not immediately return calls from The Associated Press seeking additional information.
