The East Haven mother who was found dead behind a Branford restaurant in July died of homicidal asphyxia, according to the Office of the Chief Medical Examiner.
The 27-year-old mother was reported missing on July 3 but her family told police she had been missing since June 30 or the early morning hours of July 1.
Aleman-Popoca left behind a 7-year-old daughter.
The owner of the restaurant where Aleman-Popoca's body was found told NBC Connecticut in July that a man in a relationship with the victim worked at the restaurant.
Police have not made any arrests or named a suspect in the case.
