The Polk County Sheriff's Office announced Tuesday that deputies captured 26-year-old Enrique Martinez, a man wanted as a suspect in two killings since November.

Sheriff Grady Judd said Martinez is the prime suspect in the death of 20-year-old Sierra Hernandez. But the Sheriff's Office has yet to provide details on how the Winter Haven woman, reported missing by her family on Jan. 14, met her end.

Here's what The Ledger knows so far, based on news conferences, police and court records:

Sierra Hernandez goes missing

Hernandez is a graduate of Winter Haven High School.

  • A missing-person report was filed Jan. 14.

Hernandez's car found

One day after Hernandez's family filed a missing-person report, Polk deputies arrested an individual who was driving her car:

  • Daphne Ann Fernandez, 44, of Winter Haven, was pulled over Jan. 15 by deputies while driving Hernandez's vehicle along U.S. 92/Memorial Boulevard in Lakeland.

  • Fernandez was arrested and charged with knowingly driving on a suspended or revoked driver's license.
