ANGELES CITY, Philippines ? A warrant of arrest was issued in 2005 against a man suspected of robbing and killing three foreigners and six Filipinos in three separate incidents here over the last two weeks.

However, the warrant was never served and Mark Dizon remains free for more than five years. Dizon, 28, was even able to audition for the television reality show ?StarStruck? a few years ago, police and local officials said.

Mayor Edgardo Pamintuan said Angeles Regional Trial Court Judge Philbert Iturralde issued an arrest warrant against Dizon on Jan. 13, 2005, for robbery and car theft.

In a news conference on Sunday, both Pamintuan and Chief Insp. Marcelo Banola, head of the city police?s investigation branch, could not say why the warrant was never served.

Dizon, a computer technician and reflexologist, is being hunted for allegedly robbing and killing American Albert Mitchell, 70; his Filipino wife Janet, 53; and helpers Isabel Fajardo, 29; Marissa Prado, 29; and Yulberto Catli, in Hensonville Court Subdivision here on July 22.

He is also the suspect in the robbery and killing of Briton James Bolton Porter, 51, and his live-in partner, Melissa Madarang, 22, in Sta. Maria Subdivision on July 16, and the robbery and murder of Canadian Geoffrey Allan Bennun, 60, and live-in partner Abegail Helina, 20, at the Oasis Hotel and Villas in Clarkville Compound on July 12.

Ballistic tests showed that the gun used in killing the victims came from the same 9mm pistol.

On Sunday, a local pawnshop owner turned over to Pamintuan a laptop computer, a video camera, a digital camera, camera lenses and cellular phones pawned by Dizon recently.

Banola, however, refused reporters? request to turn the laptop on to see who owned it.

Dizon was held by security guards while he was about to leave the gate of Hensonville Court Subdivision in the afternoon of July 22.

The subdivision?s security guards became suspicious and held Dizon when they noticed that he was carrying a backpack, a laptop bag and a laundry bag on his way out although he was only carrying a backpack when he entered the subdivision.

However, Dizon was able to escape by telling a guard at the gate that he would buy load credits for his mobile phone at a nearby store and would return.

When a guard checked the house of the Mitchells, they were shocked to see that the American, his wife and the three helpers were dead.
