Police this evening appealed directly to people with knowledge of missing 26-year-old Chavelle Dillon-Burgess.The post, shared on social media, said: “We know someone knows what happened ... do you want those responsible to get away with it?“What if she were your mother, girlfriend or friend?”The statement told anyone concerned about speaking up that “we can help and work together, don’t let them get away with it”.Friends of Ms Dillon-Burgess, the mother of an 18-month-old child, have not heard from her since April 11.She was reported missing by her mother on April 30, about two weeks before her 27th birthday.Police are now treating the matter as a murder.Police Commissioner Stephen Corbishley said on May 23 that it was not necessary to have found a body to launch a murder investigation.A 39-year-old man was arrested on suspicion of her murder last month, and released on bail.
