Cameron is a police detective sergeant investigating Lucy Beale's murder.
Cameron arrives with his colleague, DC Emma Summerhayes, at the Beale household, when they inform Ian Beale that his daughter, Lucy, is dead. He orders officers to search Lee Carter's bedroom and takes a DNA sample for forensics. When Max Branning changes his statement about his movements on the night of Lucy's death, Cameron returns with Emma to clarify Max and his daughter Abi's statements. Cameron searches Phil Mitchell's house in connection with a robbery committed by Jay Brown, the night Lucy was killed. It is revealed that Cameron is Emma's fiancé; when Cameron learns of Emma's affair with Max, he punches him. Emma leaves Cameron for Max. Suspecting Max's daughter Lauren Branning and Lucy's brother Peter Beale to be involved in Lucy's death, Cameron keeps them under surveillance. When Emma is suspended from her job following her affair with Max, Cameron tells Emma that it was Max who reported her. When Emma dies, Cameron is sent to collect her things from Max's house, and tells him he is not welcome at her funeral.
