A DESPERATE junkie who killed his girlfriend and unborn child in a horror crash has lost his appeal to get his sentence cut.

WGC man Damian Martin was jailed in February for seven years for causing death by careless driving while unfit through drugs. He was given a further three years on extended licence.

High on an overdose of prescription drugs, Martin was racing to a pharmacy for the heroin-substitute methadone, when he lost control of girlfriend Miranda King’s car.

He was flung across the car, hitting her. Their baby was stillborn.

The 35-year-old, who lived in Howlands House with Miss King, had never taken a driving test, held a licence or insurance and had previous drug-driving offences.

Lord Justice Toulson, sitting with Mr Justice Maddison and Mr Justice Hickinbottom, refused Martin’s appeal against the extended licence.
