Authorities say a Miami Gardens man turned himself in at a Hialeah police station on Saturday -- confessing to killing his wife and mother-in-law.
Jose Garcia, 56, faces two counts of second-degree murder.
Following the confession, Miami Gardens police officers responded to Garcia's home in the 3300 block of Northwest 175th Street and found the women dead inside, authorities said. No one else was in the home when officers arrived, police said.
Police identified the victims as Marlene Gonzalez, 47, and Carmen Alfonso, 66.
It is not clear how the women were killed.
According to family members, Garcia and Gonzalez were having marital problems and going through a separation, police said.
Garcia is currently being held without bond at Miami-Dade County's Turner Guilford Knight Correctional Center.
