The trial of the man who beheaded a British woman in Tenerife is to start on Monday. Deyan Deyanov is alleged to have attacked and killed Jenifer Mills-Westley by beheading her in a Chinese supermarket in Los Cristianos.

The 28 year old Bulgaria man is said to have stabbed her before beheading her and then dropping her head outside. The suspect has a criminal record police said, and had been treated in a psychiatric hospital in Britain a few months earlier after committing other violent attacks. The attack appeared to be random.

The refusal by the defendant to admit responsibility for the crime has forces the authorities to hold a trial, even though he was apprehended and held down at the scene by security staff.

Deyanov is described as a paranoid schizophrenic and violently delusional who became obsessed with a film about aliens who stalk there victims before beheading them.
