Marana police have released the identities of the victim and suspect in a Friday afternoon fatal shooting in the Arizona Pavilions shopping center's parking lot.

Marcus Dickson, 26, was booked into the Pima County jail Friday on one count of felony manslaughter, said Sgt. Chriswell Scott, a Marana Police Department spokesman.

The victim has been identified as 40-year-old  Martin Padilla.

Scott said investigators learned that both men fought prior to the shooting.

Detectives are working to determine what led up to the fight and shooting. 

Witnesses were also being questioned late Friday night, Scott said.

Shortly after 2 p.m., numerous 911-callers reported a shooting at the shopping complex parking lot, which is west of Interstate 10 at North Cortaro Road, Scott said.

Officers found the wounded man, and despite bystanders and Northwest Fire District paramedics giving life-saving aid to the man he was pronounced dead at the scene, said Scott.

Scott said the shooting is an isolated case and investigators said that they do not have any information about it being connected to a road rage incident.

Investigators are asking that anyone who saw or took video of the shooting to contact 911, 88-CRIME or Marana police at 382-2000, said Scott.
