ST. PETERSBURG —- A 39-year-old St. Petersburg man has pleaded guilty to second-degree murder in the death of a pregnant teenager whose body was found in Polk County.
Aurelio Martinez received a 40-year prison sentence this week in a plea agreement with the Pinellas-Pasco State Attorney's Office.
Martinez gave an interview to St. Petersburg police in which he admitted grabbing the neck of Bria Metz, 17, after an argument in 2009. After discovering she wasn't breathing, he drove to Polk County and discarded her body, authorities said.
Family members said Metz was about three months' pregnant at the time of her death.
