ST. PETERSBURG, Fla. — On August 18, 2013 Tracy Pulido, then 42, never showed up to pick up her son from a friend.

Worried, a neighbor used a spare key to get inside Pulido's apartment. There, police say they found Pulido dead after an apparent violent struggle.

Since then, the case has remained unsolved. Detectives in St. Pete hope a new $10,000 reward for information will lead to her killer.

Detectives say in the past six years, all leads have been exhausted. They believe the killer may have known Pulido or lived near her Fountain Court apartment.

If you have any information that would help bring the person or persons responsible for Tracy Pulido’s death, please call the St. Pete police non-emergency line and refer to Report# 2013-050535.
