Osmond family members have notified ET that Marie Osmond's son Michael Blosil leapt to his death Friday night in Los Angeles. Contacted by phone Saturday morning, Donny Osmond tells us: "Please pray for my sister and her family."

18-year-old Blosil, jumped to his death from his Los Angeles apartment on Friday night around 9 p.m. The Los Angeles Fire Department tells us they received a 911 call at 9:24 p.m. and were dispatched a minute later. An individual who'd fallen from a 15-story building was found dead at the scene of the incident.

He left a note explaining he intended to commit suicide due to his life-long battle with severe depression that left him, he said, feeling as if he had no friends and could never fit in.

Marie, who helped him fight the condition throughout his life, issued a statement through her publicist expressing her deep sorrow and requesting privacy.

"My family and I are devastated and in deep shock by the tragic loss of our dear Michael and ask that everyone respect our privacy during this difficult time," the statement said.

Blosil was one of Marie's five adopted children. She divorced Blosil's father in 2007. She also has three other children from other marriages.

Marie and her brother Donny starred in the hit "Donny and Marie Show" in the 1970s. The pair was scheduled to perform at the Flamingo Las Vegas Hotel and Casino Saturday night but canceled the performance.

The ongoing investigation is being handled by the LAPD and the Los Angeles Coroner's Department. An autopsy might be conducted as soon as Sunday morning.
