Police ruled the death of a Winthrop man a homicide yesterday and took a suspect into custody.
Authorities took John Lacoy, 47, into custody after statements made in an interview and additional evidence made a case for his guilt.
The victim was found under a porch earlier this week with a stab wound in his chest. Police have identified his body despite decomposition, but are not releasing his name as of yet.
Lacoy is expected to be arraigned at East Boston District Court today.
