A convicted murderer who returned to the scene of the crime was caught on body-worn camera telling an officer that he "knows what happened".
Marek Hecko, 26, was this week sentenced to life in prison (with a minimum term of 26 years) after taking the life of a married father-of-two in July last year, BBC News reports.
He had been found guilty at Chelmsford Crown Court of fatally stabbing 44-year-old Adrian Ellingford in the back at a home in Essex, United Kingdom, on July 25.
Ellingford was with Hecko's ex-girlfriend Stephanie Breame on the night he was murdered at the Chelmsford property, the court heard.
Hecko and Breame had ended their relationship in May after seven years together, with the former engaging in "stalker-like behavior" and "pining and obsessing" over her after the split. Jurors heard how the killer would show up uninvited to her place of work and home, called her phone, sent messages and looked her up online.
In bodycam footage, Hecko - who is described by police as "intoxicated" - is seen holding a bottle of brandy as he approaches the street on which the murder took place just hours earlier, reports The Telegraph.
Check out the chilling footage:Drinking from the bottle, he tells an officer: "I can help here, what is going on?"
He goes on to say: "I know what happened, I know the people that are involved, but you need to dig deep."
The officer is heard asking Hecko for his name, but he tells her: "I’m not going to tell you my name… because I know what happened and you need me to figure out what happened."
When asked about what he knows, Hecko goes on to say: "I just know that some guy came here and he f***** up some guy. I don’t know what happened."
Becoming increasingly aggressive towards the officer, he adds: "You’re going to think about me, but it is not going to be me, because there is no proof."
Attempting to understand what the man means to say, the officer asks him if he "thinks" he knows what occurred at the Nelson Grove home, to which he responds: "No, I know what happened."
He then boasts: "This city is mine."
Following the arrival of other officers, Hecko was arrested as he became increasingly confrontational outside the crime scene. Officers then identified the man as the prime suspect in the murder.
During his trial, Hecko told jurors that he arrived at the scene the morning after he heard about the stabbing on the news. However, there had been no reports published about the fatal attack at that point.
Detective Chief Inspector Louise Metcalfe of Essex Police said: "This was a senseless attack on Adrian, which has left two children without a father. I hope that they can move forward and find some closure now that Hecko is behind bars."
Mr Ellingford's widow read out a victim impact statement in court, describing her late husband as an "amazing husband, loving son, a caring brother, a friend to many and, most importantly, a truly brilliant father."
