A 35-year-old Melbourne man has been charged with one count of murder over the death of 23-year-old Celeste Manno in Melbourne’s north-east.

Luay Sako of Roxburgh Park faced an out-of-sessions Melbourne Magistrates Court hearing on Thursday evening and was remanded in custody until April 27.

Ms Manno was found dead in her Umbria Road home in Mernda about 4am on Monday.

Mr Sako was arrested by police on Monday and was in hospital for three days under police guard, until he was questioned by Homicide Squad detectives on Thursday afternoon.

“Now it seems like the best thing I can do for her,” Mr Ridsdale wrote on Wednesday when republishing the picture.

“To show everyone how much she meant to me and how beautiful she was.”

Ms Manno was a university graduate, with family describing her as universally loved and intelligent.
