American biologist Kent Carpenter, 73, was fatally shot Sunday inside his residence in the Philippines, in a case police are investigating as a murder.
Carpenter, an adjunct professor at Silliman University’s Institute of Environmental and Marine Sciences in Dumaguete City, was at home with his 34-year-old girlfriend when authorities said three men forced their way inside around 11:30 p.m.
Investigators believe the attack occurred during a robbery, with one of the intruders allegedly shooting Carpenter in the head. The suspects also reportedly restrained Carpenter’s girlfriend and sexually assaulted her, according to the government-linked Philippine News Agency (PNA).

Police spokesperson Col. Allen Rae Co told reporters the assailants escaped with a laptop, cash and a backpack.
The three suspects remained on the run, while local authorities have opened a special investigation aimed at tracking them down, PNA reported.
In a statement, police said investigators had started “conducting backtracking and forward tracking operations,” which include examining possible CCTV recordings, interviewing witnesses, verifying intelligence leads and piecing together the suspects’ movements before and after the attack.
“We strongly condemn this senseless act of violence. I have directed our investigators to exhaust all legal means to identify and apprehend those responsible at the soonest possible time,” Regional Director Police Brig. Gen. Romano Cardiño said in the statement.
“We assure the victim’s family, the community, and our foreign visitors that this case is being treated with utmost urgency, and no effort will be spared until justice is served,” he also said.

Carpenter was a highly renowned scientist who studied fish, co-authoring a 2005 study that crowned the Philippines’ Verde Island Passage as “the center of marine shore fish biodiversity.”
He spent decades working as an ichthyologist, collaborating with Silliman University in some capacity since 1976.
“Dr. Carpenter made groundbreaking contributions that transformed global understanding of Philippine marine biodiversity,” Silliman University said in a statement.
“Dr. Carpenter’s contributions to Philippine marine science were profound and enduring,” a statement the Philippine Association of Marine Science posted Tuesday read.
“As a U.S. Peace Corps volunteer in the 1970s, he worked with the Bureau of Fisheries and Aquatic Resources and helped train the country’s first coral reef science team. His early papers on Philippine coral reef fisheries resources, including his work with National Scientist Angel C. Alcala on muro-ami and kayakas reef fisheries, were landmark contributions that shaped the country’s understanding of reef fisheries and the urgent need for science-based management,” the statement continued.

“In the wake of this devastating loss, PAMS strongly condemns this act of violence. We call upon the Philippine National Police, the local authorities in Negros Oriental, and appropriate national investigative agencies to conduct a swift, thorough, and transparent investigation. Those responsible for this heinous crime must be held fully accountable under the law,” the statement added.
“Dr. Carpenter devoted his life to protecting the Philippines’ marine heritage. We owe it to him to honor that legacy by continuing his work and demanding justice for his tragic and untimely death,” the statement concluded.
