New details are emerging about the death of Martin Short's daughter, Katherine.

The official death certificate for the *Three Amigos* star's daughter, which was published by TMZ, states that Katherine was cremated after she died by suicide at 42 last week.

The document states that Katherine died from a self-inflicted gunshot wound to the head, and that there were no other significant conditions that contributed to her death.

The death certificate also stated that the specific date and time of her injury were both unknown, though a report from the County of Los Angeles Medical Examiner's office listed Monday, Feb. 23 as the date of Katherine's death.

A representative for the *Only Murders in the Building* star previously provided a statement to EW that confirmed Katherine's untimely death.

"It is with profound grief that we confirm the passing of Katherine Hartley Short," the statement said. "The Short family is devastated by this loss, and asks for privacy at this time. Katherine was beloved by all and will be remembered for the light and joy she brought into the world."

The Los Angeles Fire Department responded to a call from a house in Hollywood Hills around 6:41 p.m. on Feb. 23, PEOPLE previously reported. The call concerned a woman in her early forties, and the Los Angeles Police Department told the outlet that the call regarded a possible suicide.
