Killer: Hazel Stewart waived her right to anonymity to bring fresh allegations against former dentist Colin Howell

Double killer Colin Howell told police he injected his former lover Hazel Stewart with a drug used to sedate intensive care patients to remove “the guilt” of having sex with the man she had helped to murder her husband.

The details are contained in a decision by the North’s Public Prosecution Service not to charge the Coleraine dentist for the rape and sexual assault of the former Sunday school teacher.

Stewart waived her right to anonymity last year to allow the fresh allegations against Howell to be reported.
