A woman's Facebook post moments before she was killed led police to the man suspected of killing her, another woman and 6-month-old boy, police said.

Miami-Dade police picked up Lineten Belizaire, 20, on Sunday.

Belizaire was arrested in connection with the shooting deaths of Natasha Plummer, 25, her 6-month-old son, Carlton Stringer Jr. and Octavia Barnet, 21, who were found dead inside a Lauderdale Lakes apartment last week.

Barnett’s 11-month-old son survived the incident. 

Police said a Facebook posting by Octavia Barnet led them to Belizaire. According to police, Barnet posted that Belizaire was at her door and that she was scared.

He has the same last name as the 11-month-old boy whose life was spared by the killer. Lineten Belizaire's name is on the child's birth certificate.

No bond has been granted to Belizaire, who is awaiting transfer to Broward County.

Belizaire is a graduate of Northwestern Senior High School, class of 2009. He was a standout cornerback for the Bulls.
