She continued: “I wish your short time here was easier and I hope your mind is at ease now.”
Her central promise was: “I will honor you forever and keep your memory alive.”

They remembered Fiona as a loving, clever and creative girl who adored dancing. Their statement said her sisters adored her and described Fiona as the light of their lives. The couple asked for prayers and privacy as the family mourns.
Fiona died in Los Angeles on Tuesday. A medical examiner confirmed on Thursday that she had died by suicide.
