Norbert Maiksner, 49, was found by officers wandering alone on the hard shoulder of the M40 in the early morning of April 17 last year. Hours before, he had killed his girlfriend, 45-year-old Frances Obiefuleh, at their home in Havant, Hampshire. Maiksner told the officer to call the police because he had killed his girlfriend.
The man was convicted following a trial at Portsmouth Crown Court.
