A grand jury has indicted 37-year-old Milton Marrero (DOB 7/17/1982) of Deltona on a charge of first-degree murder in the April overdose death of Mark Guerin Jr.
Marrero was indicted on Monday and was already in custody at the Volusia County Branch Jail, where detectives arrested him on his murder charge.
Guerin was found dead on April 5 along Lake Helen Osteen Road, and it was later determined he died as a result of an overdose on fentanyl.
Volusia sheriff’s deputies have arrested Marrero multiple times, including an arrest after a traffic stop in November 2018, when a deputy found him in possession of a trafficking amount of heroin, small plastic baggies, multiple used syringes and a loaded firearm. He was later released on bond, then arrested again April 23 of this year (about 3 weeks after Guerin’s death) after another traffic stop, and again on May 29 after his bond was revoked.
This case is the fifth murder indictment that the Volusia Sheriff’s Office has obtained in an overdose death investigation since 2017. The other four are:
