The other defendants were Antonio Lejano II, Hospicio Fernandez, Michael Gatchalian, Miguel Rodriguez, Peter Estrada, Joey Filart and Artemio Ventura.

With the exception of Filart and Ventura who had been convicted in absentia the men were acquitted by the Supreme Court on December 14, 2010, for failure of the prosecution to prove guilt beyond reasonable doubt.

The Vizconde murders remained unsolved for almost four years, until eyewitness Jessica Alfaro, a self-confessed former drug addict, came forward on April 28, 1995, to shed light on the massacre.

Alfaro implicated the children of wealthy and prominent families, including Hubert Webb, Antonio Lejano II, Hospicio Fernandez, Michael Gatchalian, Miguel Rodriguez, Peter Estrada, Joey Filart and Artemio Ventura.

Webb wanted Alfaro, the then-girlfriend of one of the accused men, Peter Estrada, to join them because Estrellita Vizconde only allowed her daughter to go out and entertain female visitors.

Alfaro also said that she bumped into Biong at the Faces Disco in Makati in March 1995 and relayed to her the offer of the group to give her a free ticket to the United States to shut her up.

She added that suspect Miguel Rodriguez warned her to "shut up or you're gonna get killed" in the same disco on April 8, 1995, prompting her to voluntarily submit herself to the National Bureau of Investigation (NBI) for protection.

The defense questioned Alfaro's credibility noting that she admitted to being under the influence of drugs when she allegedly witnessed the crime and had made inconsistent statements on her two affidavits.

808 bound for New York and who expressed doubt on whether Hubert Webb was his co-passenger in the trip; NBI medico-legal Dr. Prospero Cabanayan, Belen Dometita and Teofilo Minoza, two of the Vizconde maids; and Manciano Gatmaitan, an engineer.

This coincided with his passport and Philippine Immigration records but were dismissed by Tolentino due to belief that these documents can possibly be falsified.

According to Rivera, Sacaguing was never part of the NBI team assigned to investigate the Vizconde massacre and that his former colleague took Alfaro's statement in April 1995 without the presence of a lawyer.

[17] On January 6, 2000, Judge Tolentino rendered her decision, finding Hubert Webb, Peter Estrada, Hospicio Fernandez, Michael Gatchalian, Antonio Lejano II and Miguel Rodriguez guilty beyond reasonable doubt of the crime of rape with homicide.

[19] The Court of Appeals' Third Division voted 3–2 to deny Webb's motion for reconsideration and upheld the ruling of Judge Tolentino on December 16, 2005.

The court also amended the award of damages from 100,000 pesos to 200,000 pesos, and also upheld the conviction of Biong as accessory to the crime "by abusing his public functions... to conceal and destroy the physical evidence in order to prevent the discovery of the crime and by allowing the destruction of the physical evidence, Biong facilitated the escape of the principal accused.

"[21] In April 2010, the Supreme Court approved DNA testing to be performed on the semen specimen obtained during autopsy from Carmela Vizconde.

[23] On November 26, 2010, Lauro Vizconde voiced his concern to media about the purported lobbying of Senior Associate Justice Antonio Carpio for the reversal of the guilty verdict.

[27][28] Seven justices based its decision on the following points: Webb, citing Brady v. Maryland, said "that he is entitled to outright acquittal on the ground of violation of his right to due process given the State’s failure to produce on order of the Court either by negligence or willful suppression the semen specimen taken from Carmela."

The court considered the accused's "lack of interest in having such test done" in which they concluded that the state "cannot be deemed put on reasonable notice that it would be required to produce the semen specimen at some future time".

[29] The court also held that the testimony of the Webb's maid, Mila Gaviola, was also unreliable since she was not able to distinguish if it was Hubert whom she saw on June 30, 1991, nor "did she remember any of the details that happened in the household on the other days".

Webb's travel documents and other paper trail of his stay in the US are unreliable proof of his absence in the Philippines at the time of the commission of the crime charged.

In this case, the existence of an earlier negative report on the NIIS record on file concerning the entry of appellant Webb into and his exit from the US on March 9, 1991, and October 26, 1992, respectively, had raised serious doubt on the veracity and accuracy of the subsequently issued second certification dated August 31, 1995, which is based merely on a computer print-out of his alleged entry on March 9, 1991, and departure on October 26, 1992.

[48] President Benigno Aquino III ordered the law enforcement agencies to re-investigate the case six months before the prescription period lapses in 2011.

[59] The witnesses include an electrician, a drug dealer, a couple of neighborhood basketball players, a hairdresser and a village security guard.

Pitong, an electrician who since 1982, already knew the Webb family claimed he saw a laundry woman wash a bloodied T-shirt on the morning of the crime.

[62] Mario, a hair stylist during the period June 1991, testified that Webb, along with Tony Boy Lejano and Dong Ventura had their haircut.

[67] One team uncovered “Black Maria,” a woman whom one witness said had told him she was with Webb's group inside the Vizconde home and saw the crime take place.

“She admitted to knowing Webb and company but denied knowledge of the Vizconde massacre,” NBI Death Investigation Division head Romulo Asis said.

De Lima said it was possible that it was Black Maria who was in the Vizconde home and not Jessica Alfaro, the NBI's star witness during the trial.

[62] Although Webb's group can no longer be retried because of double jeopardy, De Lima said the purpose of the reinvestigation was to “uncover the truth” and bring closure to Lauro Vizconde.

[69] The 1995 film The Jessica Alfaro Story, directed by Francis 'Jun' Posadas, focused on the titular witness, portrayed by Alice Dixson.
