Errol’s death has hit AJ hard, in the second and concluding part of the opening story of a new series of the medical crime drama Silent Witness. When Levi stops coming to the youth centre, AJ despairs that he or anyone can ever actually make a difference to the kids’ lives. Leo doesn’t want him to give up hope. He talks to Levi and tries to encourage him to tell the police what he knows about the murders. But Levi is too scared to “squeal” on Keenan. Instead, he’s pushed forward to kill a member of the Somali crew and retrieve Keenan’s drugs. Levi is unable to carry through the stabbing and runs away – leaving Keenan and his cohort to finish the job.

A shaken Levi turns to Leo for help and finally confides all that he knows. Leo relays the information to DS Wallace. But the police are unable to secure any concrete evidence against Keenan, who manages to evade their net and corner Levi in the park. He sets his dog on Levi and the vicious attack kills him. Leo is distraught.

Finally, just when it seems that all hope of catching Keenan has gone, the team make a breakthrough. But will their efforts ever be enough to make a difference to the lives of the kids on these estates?
