1 detained after man, woman found dead in southwest Miami-Dade, sheriff's office says

One person was taken into custody in southwest Miami-Dade on Friday morning after two people were found dead, according to the sheriff's office.

The Miami-Dade Sheriff's Office said that just after 8:30 a.m. Friday, deputies responded to reports of a possible woman found unconscious in the area of Southwest 209th Place.

When deputies arrived, they said they found a woman and a man dead.

Miami-Dade Fire Rescue arrived at the scene and pronounced both adults dead. The identities of the victims have not been released as of publication, though relatives who spoke with CBS News Miami off camera identified the victims as a couple in their 50s, and said they are struggling to understand who could have wanted to harm them.

In addition, an adult man has been detained pending the investigation. Investigators have not publicly identified him, and have not disclosed what led detectives to detain him.

"Everything was calm here," said a worker at a nearby nursery who was shocked by the discovery.  "They were good people," he added.

Miami-Dade Sheriff's Office Homicide detectives have taken over the investigation, which they have defined as a double homicide. Anyone who saw suspicious activity, heard anything unusual, or has information that may assist investigators is asked to contact Crime Stoppers Miami-Dade at 305-471-TIPS (8477).
