We don't know Denise is dead.

When Lucas' ex-wife Trina (Sharon Duncan Brewster) began interfering in their relationship, Lucas was instrumental in her death,[8] and went on to kill Owen when he came close to discovering the truth.[9] In May 2010, Green reported that in an upcoming episode, Lucas would be seen to strangle Denise and dispose of her body in a canal. He questioned whether Parish was to be written out of the soap,[10] following the announcements that both Benjamin and Owusu would be leaving EastEnders later in 2010.[11][12] Discussing the storyline, Gilet refused to reveal whether Lucas would kill Denise, but indicated that events may not be as they seemed.[13] Parish commented: "It looks really bad as he gets Denise in a headlock and chokes her. If she survives, it'll be a miracle."[14] Following the episode where Denise appeared to be strangled by Lucas, Entertainment journalist Sharon Marshall appeared on This Morning, saying there would be "twists and turns" but would not confirm whether Denise was dead or alive.
