A HEAVILY-PREGNANT woman was killed in a car crash when her boyfriend was flung across from the driver’s seat, hitting her “like a blunt instrument”.

High on an overdose of prescription drugs, Damian Martin was racing to the pharmacy for his next fix of heroin-substitute methadone, when he lost control of girlfriend Miranda King’s car on Birchall Lane, WGC.

On Monday at St Albans Crown Court Martin, 35, admitted causing her death by dangerous driving while unfit through drugs.

The couple’s son, due to be called Kieran, was delivered by Caesarean after the crash in July 2008, but was stillborn.

The 35-year-old convicted drug dealer lost control of Miss King’s Peugeot 206 on a bend, but as he was not wearing a seatbelt, his own arm was ripped from its socket as he was thrown around inside the car.

A passing Vauxhall Corsa was forced off the road and its 24-year-old driver was trapped with both legs and an elbow broken.

Martin was airlifted to hospital in Harlow, while Miss King, who also suffered a broken neck through severe whiplash, was taken to the QE2 where her baby was delivered.

Miss King, already a mother-of-four, of Howlands House, WGC, later died. She was 39.

Barry Gilbert, defending, said Martin had been taking drugs since he was 12.

He said: “It’s undeniably a tragedy for him. His partner and his unborn child have gone.”

Judge Michael Baker remanded Martin in custody, but delayed sentencing for reports.

He said: “He’s never had a licence, been frequently disqualified and was disqualified at the time.

“I have serious concerns about him being dangerous, having regard to his persistent driving while disqualified.”
