Giovanni Ramirez not yet charged

Los Angeles prosecutors have yet to charge Giovanni Ramirez, the suspect in the beating of San Francisco Giants fan Bryan Stow at Dodger Stadium on Opening Day, despite meeting with detectives from the Los Angeles Police Department Tuesday afternoon.

The police generally have 48 hours after an arrest to bring information related to the case to the D.A.'s office, which then reviews the information and decides whether to file charges.

However, Ramirez will remain in custody on a parole hold, pending the outcome of a parole revocation hearing, while detectives continue their investigation, the LAPD said in a statement on Tuesday.

Chip Matthews, who is representing Ramirez, told The Associated Press Tuesday that his client is willing to take a polygraph test to show he was not at the stadium when Stow was viciously attacked.

 Matthews says Ramirez spent the day at his aunt's house with several family members who are willing to testify he was with them.

Ramirez, 31, who has two prior felony convictions, was booked Sunday evening on suspicion of assault with a deadly weapon. He was apprehended in an early-morning raid by LAPD SWAT officers at an East Hollywood apartment complex after an intense, seven-week manhunt.

The district attorney's office had no comment when reached by ESPNLosAngeles.com late Tuesday afternoon. On Monday, a spokeswoman said the D.A.'s office was "reviewing the arrest."

Police said that a tip from Ramirez's parole officer was the key break in the case.

Because the Los Angeles Police Department continues to investigate the March 31 beating of Stow, the D.A.'s office said it would have no further comment.

Stow remains in critical condition at San Francisco General Hospital.

The investigation was complicated on Monday however, when photos of Ramirez were leaked to several news agencies, which briefly posted them on their websites, according to the Los Angeles Times.

The Times, citing unnamed law enforcement sources, reported on its website Tuesday evening that the delay in charging Ramirez was not a reflection of the strength or weakness of the evidence against Ramirez, but a routine procedure.

Detectives have scheduled a physical lineup for Wednesday, the Times reported, where witnesses to the assault on Stow will be asked whether they can identify the attacker.

Previously, police have only shown those witnesses photographs of Ramirez.

Los Angeles police chief Charlie Beck said Sunday that Ramirez is believed to be the "primary aggressor" in the Stow beating. Police are still looking for the other suspect in the attack, and a woman wearing an Andre Ethier jersey who helped the suspects flee in a white Mitsubishi or Acura after the attack. Witnesses have described her as a 5-foot-2 or 5-foot-3 Latina in her 20s with brown or dyed hair in a ponytail.
