MANILA - Businessman Dennis Sytin submitted a counter-affidavit on Monday denying responsibility in the killing of his older brother Dominic.
In his counter-affidavit Sytin said he was "not capable of murder" and cited the negative results of his polygraph test.
"I am not capable of murder. I have no derogatory record," Sytin said.
"I voluntarily submitted myself to a polygraph test conducted by the NBI technicians and passed the same. My full cooperation in the investigation and favorable polygraph test results show that I do not have a guilty conscience," he added.
The older Sytin, founder and chief executive officer of United Auctioneers Inc. (UAI), was shot dead in front of Lighthouse Hotel at the Subic Bay Freeport Zone on Nov. 28, 2018.
His bodyguard, Efren Espartero, was also wounded in the attack.
Respondent Sytin is facing murder and frustrated murder complaints, along with self-confessed gunman Edgardo Luib, and a third person, Oliver Fuentes, alias Ryan Rementilla.
Sytin has denied any involvement but police are looking into an alleged fight for control of shares in UAI, one of the country's biggest auction firms, prior to the killing.
Luib was arrested in Batangas last March 5 for a different murder case. He admitted to shooting Dominic Sytin and Espartero allegedly upon the order of the younger Sytin in exchange for money. - with a report from Mike Navallo, ABS-CBN News
