One day after identifying Peca as the victim, St. Petersburg Police named Benjamin "Bambi" Williams, 38, as their suspect in the investigation.
Police said Williams and Peca were in a relationship and they had a child together. Peca was reportedly holding their infant when Williams allegedly shot her in the face. Peca's older child was in the back seat at the time of the shooting.
St. Petersburg Police issued a warrant for Williams's arrest and said he is linked to several homicide investigations. Police said he's considered armed and dangerous. A $5,000 reward was offered for information leading to an arrest.
