Ghaziabad, Feb. 5 -- In the hours after three half-sisters jumped to their deaths from the ninth floor of their apartment in Ghaziabad, investigators began piecing together a portrait of a family that lived together but rarely connected - and of three girls who, police said, had slowly withdrawn not only from the world outside but even from their own family. An eight-page suicide note recovered from the apartment has revealed that the girls did not "like" their half-brother or other family members, investigators aware of the case details said, because they felt no one around them understood their deep fascination with Korean culture. Investigators said the sisters were so immersed in K-dramas and K-pop. They had abandoned their given names and took on monikers of Aliza, Cindy, and Maria, which investigators said they used consistently within their self-contained world. "The girls had completely internalised this alternate identity," said a senior police officer familiar with the investigation. "In the note, they repeatedly mention how no one - not their brother, not other family members - understood their love for Korea." The officer said the note explicitly stated that the girls did not like their half-brother, referring to him only as "bhai", and complained that he and other family members failed to respect their interests. "They had a single phone which they used to watch shows. They also had a TV which they used to watch K-drama and movies. They wrote in the note that they liked Korea, China, Japan and Thailand, and that they liked people from those places. They were upset that they could not go and live there." Investigators said the three sisters were inseparable. "They bathed together, ate together, slept together, and even went to the washroom together," the father told police during questioning. Ravi Balyan, station house officer of Tila Morh police station, said the 14-year-old appeared to be the dominant figure. "She was the 'leader'. If she skipped a meal, the other two also wouldn't eat. They spent entire days together," he said, adding that she wrote the suicide note. The girls had little interaction with others, including their brother. They did not attend school, rarely stepped out, and had no known friends in the neighbourhood. "They did not have a social life at all," an officer said. Police said the sisters had stopped going to school around 2020. The eldest had studied till Class 7, the middle one till Class 5, and the youngest till Class 3. Before that, the eldest had briefly attended a school in Nainital. Investigators believe tensions escalated in the days leading up to the incident after their father restricted their access to phones and the internet. The girls shared a single mobile phone, which they used to watch K-dramas. Police said the father sold the phone for Rs.3,500 -possibly due to mounting financial stress - and had also forced them to delete a social media account with around 2,000 followers about 10 days earlier. "This angered them deeply," an officer said. "Their online world was everything to them."...
