Man, 33, arrested and charged in murder at Tampa church

Police say they have a person in custody in connection with a death investigation at Christ the King church and school on South Dale Mabry Highway.

A body was discovered in the parking lot, and 33-year-old Michael Marston of Tampa has been arrested and charged with second-degree murder.

"Definitely surprised this morning," said Tim Pfister, who works across the street. "We came in at 7:30 cops were all over the place."

Police say he violently attacked a man and then fought police as they tried to arrest him. According to police, it happened in the parking lot of the well known church.

Police say Marson got into an argument with 83-year-old Rolando Rivera-Arroyo early Thursday morning. Detectives say Marston stabbed him, ran him over with his car and then walked away from the scene.

"Totally unexpected - never anticipated something like this would occur on church property," church member Dan Gallagher said.

Marston was found not too far from there a few hours later, walking along Henderson Boulevard and Swann Avenue. He was taken to Memorial Hospital for a broken finger.

Detectives then identified him as the murder suspect and tried to arrest him, but police said he fought back violently.

Police also say before the murder Marston broke into the storage unit at his ex-wife's apartment and stole several items that were later found at the murder scene.

Right now, police can't find relatives for Rivera-Arroyo. They believe he might have been homeless.

Police are still trying to determine a motive.
