MIAMI -

A man suspected of killing a baby and two women is back behind bars.

Police rearrested Lineten Belizaire after they said they found a weapon in his car during a traffic stop in Miami.

Belizaire was arrested in January in connection with the deaths of Natasha Plummer, 25, her 6-month-old son, Carlton Stringer Jr., and Octavia Bennett, 21.

The three were found fatally shot in a Lauderdale Lakes apartment.

Belizaire was released from custody earlier this month as prosecutors continued to look for more evidence.
