Tracy police are investigating a reported rape from early Friday morning at Tracy Ball Park.

Police arrested Francisco Alfredo Garcia, 22, and Antonio Daniel Marquez, 25, both of Tracy. Garcia was booked on suspicion of rape and oral copulation and is being held in San Joaquin County Jail in French Camp on $525,000 bail. Marquez was booked on suspicion of oral copulation and is being held on $75,000 bail. They both will appear this afternoon at the Tracy Courthouse, where they are likely to enter pleas. Police say the victim is a 17-year-old Tracy girl.

Tracy police Capt. John Espinoza said the incident started as about 10 people, including teenagers and adults, gathered to drink at the park. Investigators said the girl knew the men but resisted them when it became apparent that they wanted to have sex with her. Investigators said at least two other people saw the rape.

Police received the initial call at 12:40 a.m. Friday after someone called and said some young men were taking things from some young women in the bleachers at the park, 2001 Bessie Ave.

The person told police that it also appeared that someone was being raped.

Police then got a call from a young woman, who said she was afraid to give her name or much more information because the men had threatened to kill her if she called police. She told dispatchers that the men took her friend toward the backstops at the park and raped her there.

Police arrived within five minutes of the initial call and started to talk to four people, including a young woman who said she was the victim’s friend, as they walked away along Grant Line Road. An officer found the girl walking away from the park, and other officers stopped Garcia and Marquez in the park.
