The mother of a 13-year-old girl who has been missing for six days has made an emotional plea for her safe return. Lillia, from Bolton in Greater Manchester, was last seen at 1:50 p.m. on Saturday at the Trafford Centre, a large shopping complex. She boarded a 247 bus heading towards Altrincham, but it is unclear how long she remained on the bus or where she might have gotten off. Authorities are still searching for any information that could help locate her. Lillia is described as white, slim, around 5 feet 5 inches tall, and wears glasses. She has light brown hair and was wearing a black zip-up hooded top, light blue baggy jeans, and a black Nike backpack. Her mother, Jessica, sent a direct message expressing her deep concern: "Lill, I love you so so much. My heart is breaking without you here. I need to know you are safe. We all need you back home safe and well." Greater Manchester Police have conducted "extensive inquiries" since Lillia was reported missing on Friday and continue to work tirelessly to find her. Chief Superintendent Helen Critchley emphasized that the last confirmed sighting of Lillia is a key part of the investigation. The district commander for Bolton added that police are asking anyone who was on the bus and might have seen Lillia to come forward. They also want to hear from anyone who might have CCTV or Ring/Doorbell footage that could be relevant to the case, or anyone who has had any contact or conversations with Lillia since she went missing. In a heartfelt message to Lillia, police urged her to know that her family loves and misses her and just wants to know she is safe. They assured her she is not in trouble and that they simply want her to come home. The community is being asked to help in any way possible to locate the missing girl.
