Edmonton police have charged a young offender from Saskatchewan in the killing of John Kwiatkowski last year.
Kwiatkowski, 29, was the victim of a random killing, said investigator Det. Colin Derksen.
The suspect, who was a youth at the time of the killing and unlawfully at large, is charged with second-degree murder and break and enter.
A Canada-wide arrest warrant had been issued for him after he escaped from open custody at a youth facility in Saskatchewan.
Police said he killed Kwiatkowski just days after arriving in Edmonton.
Suspect in jail on separate charges
Kwiatkowski and the teen did not know each other and organized crime was not a factor, police said.
"John was the victim of a random break and enter and an unprovoked attack in his own home," said Derksen.
The suspect is currently serving time in a Saskatchewancorrectional facility for an unrelated conviction.
While police have said they believed more than one person was involved in the killing, they feel confident they have
arrested the person responsible, said Derksen.
No additional suspects are being investigated at this time, said police.
Victim's body discovered by wife
Kwiatkowski was found dead in his east-end home at 34th Street and 103rd Avenue by his wife on the morning of April 14, 2011.
Kwiatkowski's wife was returning home after working a night shift, expecting to find Kwiatkowski awake and preparing to leave for work, but instead found the home dark and quiet, police said.
She soon discovered the body of her husband, who had suffered massive injuries, said Derksen.
"We know the house was likely left unlocked and insecure overnight and so was a crime of opportunity," he said.
The couple's two-year-old daughter who witnessed her father's killing, was also hurt, he said, although he did not specify what injuries she suffered.
Police took the rare step earlier this year of producing a video revealing evidence collected in the investigation.
Last month investigators linked a string of vehicle thefts in Regina and Saskatoon to Kwiatkowski's death.
