Tracy Police Department Lt. Wade Harper said police received a 911 call for a fight at Mars Court and Gandy Dancer Drive at 11:03 p.m.
According to Harper, a sergeant responding to the call saw a four-door white sedan fleeing the area heading north on Tracy Boulevard and tried to stop the vehicle.
Harper said the sedan failed to yield to the officer, and a short pursuit along Tracy Boulevard began.
The car continued north on Tracy Boulevard and crossed Schulte Road, Harper said, and the driver pulled over to the side of the road about 50 yards north of the intersection.
When officers approached the car, Harper said they found it occupied with several people, including a male minor with an apparent gunshot wound.
Harper did not provide details regarding the wound, except that it was not life-threatening. The victim, whose name Harper did not disclose, was taken to Sutter Tracy Community Hospital, where Harper expected him to be treated and released.
The other occupants of the car were uninjured, Harper said. Except for the driver, Harper said the occupants were all minors.
The driver of the car Daniel Garcia, 19, was arrested at the scene for alleged failure to yield. Harper said additional charges could be added later.
Police cruisers blocked off a lane of Tracy Boulevard as officers and a crime scene technician examined and photographed the car.
Tracy police and California Highway Patrol cruisers also closed the entrance to Gandy Dancer Drive, the area where police believe the shooting occurred.
Gandy Dancer Drive leads to a row of businesses in an industrial-style complex off Mars Court.
Businesses in the complex include dance studios, a fitness camp and Heartland Church.
Police officers tried to find witnesses to the shooting and fight that they believe happened during a party at one of the businesses.
Harper could not say what type of party was going on, but described the party’s crowd as a mix of young people ranging from older teenagers to people in their early 20s.
Harper did not have a description of the alleged shooter, but said police believe there is only one person responsible.
Most of the crowd was leaving the scene as officers arrived, and Harper said officers were having trouble getting information from the crowd about the fight and the shooting.
He added that there was a large number of minors at the scene, and stressed parents should know where their children are to keep them safe.
Groups of young people could be seen walking north on Tracy Boulevard after they were released from questioning by the police.
Crime scene technicians examined the car on Tracy Boulevard and the scene of the fight.
No one else was injured in the fight off Mars Court.
Harper said the shooting investigation is ongoing.
