MANILA, Philippines - Four law students accused of mauling and shooting a fellow law student were charged with frustrated murder by the police Sunday at the Makati City Prosecutors Office.

Insp. Tomas Chu of the Makati Police Department identified the four as Mark Bryan Magno and his brother, Mark Lester, both residents of Filinvest, Quezon City; Carlos Lim, of Pilar Village, Las Piñas; and Randy Echaus, of Valle Verde Mansions in Pasig City.

Mark Bryan and Echaus are schoolmates of the victim, Don Albert Phillippe Pangcog, 29, who is a second year student of the Ateneo de Manila Law School in Rockwell Center, Makati.

Mark Lester and Lim, on the other hand, are taking up law at Lyceum of the Philippines University.

Among the four, only Mark Bryan is in the custody of the Makati police. He was invited for questioning on Saturday.

Based on a police report, the four beat up Pangcog as he was about to enter his boardinghouse on Palma Street in Barangay Poblacion, Makati, at around 10:45 p.m. on Friday.

One of them then shot him in the groin although the police and the victim have yet to identify the gunman.

Pangcog was later treated at the Makati Medical Center for a gunshot wound and several cuts on the head.

The victim said in his affidavit that he was opening the gate to his boardinghouse on Palma Street, Barangay Poblacion, Makati City when two men wearing bonnets came up from behind him and hit him with clubs.

He added that he fought back and that he recognized his attackers as Mark Lester and Lim after he managed to rip off their bonnets.

Pangcog said that at this point, Mark Bryan and Echaus joined the fray and started pushing him inside a Toyota RAV-4.

He added that a “dark-colored man in a black jacket” began pulling him inside the sport utility vehicle as he continued to resist.

Pangcog said that as he pulled at the unidentified man’s jacket, he “saw a spark” and realized that he had been shot.

His attackers then fled on board the RAV-4 as he sought help from people inside the boardinghouse.

Chu said a security guard at a nearby condominium also testified on the mauling and shooting incident.

Asked if he knew why he was attacked, Pangcog told investigators that he had no idea.

The Makati police, though, is looking into the possibility that the incident could be related to a fraternity-related squabble.

Chu, meanwhile, urged the three other suspects to surrender to authorities or face arrest as a case had already been filed against them.
