PREVIOUSLY,
While at the table eating with his dear wife, Alex got a call from his men about Xavier's departure from the cell they left him and Amelia's sudden death, he panicked. Not because he was scared, he knew quite well Xavier will not be able to touch his wife ever again, but he was not sure when it came to her family.
Hearing that Amelia was dead, Alex wondered who the next person might be. The man was in his revenge form and could kill anything and anyone.
Alex quickly dropped off his wife with her family before heading out to the crime scene. He hoped his men will be able to find Xavier in time before he escapes, else they'll never live peacefully knowing he could attack at any time.
Alex stepped into the cell which held Amelia, her cold empty body was found lying lifeless in the cell, they had no idea what happened to her, there was no evidence that she was murdered, and no evidence that she committed suicide.
