Over the course of a year, Sako, the obsessed stalker, bombarded the 23-year-old Celeste with countless messages expressing his love. These messages, sent through various Instagram accounts, ranged from creepy to lewd and menacing. When Celeste pleaded with Sako to stop, his reaction was alarming. He responded, stating, "I really just wanted to speak with you, and I honestly thought you were ignoring me. My impression of you has changed. You're no different from the majority of women."

Tragically, just hours after Celeste shared a picture with her new boyfriend on Instagram, Sako forcibly entered her bedroom with a hammer and stabbed her 23 times with a kitchen knife. The cause of death was a stab wound to the heart, with Celeste exhibiting defensive wounds on her forearms and arms as she attempted to protect herself.

Investigations revealed that Sako actively monitored Celeste's Instagram and even had a screenshot of the photo depicting her happiness with her boyfriend. Following the brutal attack, Sako drove to the police station and disclosed the location of Celeste's lifeless body.

In the aftermath of this horrifying incident, Celeste Manno's social media photos, once joyful, now serve as a haunting reminder of the tragedy that unfolded in her own bedroom at the hands of Luay Sako. Sako has since appeared in court, facing the consequences of his heinous actions.
