Philippine police have arrested three suspects in connection with the killing of a distinguished American marine biologist, Kent Carpenter, 73, at his home in the central Philippines. The incident, which occurred Sunday in the coastal town of Sibulan, Negros Oriental province, is believed to have stemmed from a robbery.
Authorities allege that three men broke into Carpenter's house, and one is suspected of shooting him in the head with a handgun while he was seated. Another suspect is accused of forcing Carpenter's Filipino companion into a room and raping her. The suspects reportedly fled with a laptop, cash, and a backpack.
One of the arrested individuals had previously been employed by Carpenter for carpentry work at his residence. Police identified this suspect as the alleged gunman. A fourth suspect, who allegedly acted as a lookout, surrendered to authorities and provided information that aided in the arrests.
Police spokesperson Col. Allen Rae Co stated that initial findings suggest the attack was not related to Carpenter's scientific work, but rather a planned robbery. Investigators are continuing to examine the motive behind Carpenter's killing.
Carpenter, a longtime lecturer and researcher at Silliman University in Negros Oriental, also held a position as a biological sciences professor at Old Dominion University in Norfolk, Virginia, since 1996. His research, which focused on the Philippines and the Coral Triangle region, has influenced conservation efforts globally. He was on an extended research assignment in the Philippines and had planned to retire in September.
Carpenter's expertise was previously utilized when he testified for the Philippine government in its international arbitration case against China concerning disputes in the South China Sea. His testimony as a biodiversity expert addressed the environmental consequences of China's island-building and fishing activities in the contested waters. In 2016, an arbitration panel in The Hague invalidated China's extensive claims, citing environmental damage caused by China's construction activities in the disputed areas. China did not participate in the arbitration and rejected the ruling.
