A violent rapist who was caught after giving police a sample of his own DNA has been jailed for 14 years.
Jozef Janczura, 34, attacked an 18-year-old student in Riverside Park, Southampton, in December 2018.
His victim “thought she was going to die” as Janczura choked, suffocated and strangled her to the point of unconsciousness, detectives said.
Police said he told her “sorry” as he walked away. Janczura was found guilty of rape at Southampton Crown Court.
Janczura, of Laburnum Road, was also convicted of assault causing actual bodily harm. He also faces a six-year extension which could be served in custody, the judge said.
The court heard he was caught after CCTV showed him following another woman and then the victim on the night of the attack.
The images led detectives to suspect the rapist lived in an area of the city known as the Flowers Estate.
Police asked 137 men on the estate, including Janczura, for a DNA sample. No-one refused.
Det Insp Roger Wood, from Hampshire Constabulary, said: “It could be that he felt that if he didn’t take part he would have given the game away, or didn’t think that we’d be able to do anything with it.”
Janczura was described as “predatory” by police and was seen hanging around students’ halls of residence “looking for targets”.
