Kian delos Santos, Carl Arnaiz and Reynaldo de Guzman were three teenagers who were killed on August 16 to 18, 2017, during the course of the Philippine drug war.

On the evening of August 16, 2017, a 17-year-old Filipino student named Kian Loyd delos Santos was fatally shot by police officers conducting an anti-drug operation in Caloocan, Metro Manila. The case became controversial when the official police reports differed from witness accounts and CCTV footage.

Two days after the killing of delos Santos, Arnaiz and de Guzman went missing from their Cainta, Rizal, residence. Their bodies were later found with Arnaiz reported to have been shot dead by police while de Guzman was stabbed 30 times and found in a creek in Gapan, Nueva Ecija.

The murders sparked widespread controversy across the Philippines, and has been scrutinized by the International Criminal Court. As of 2023, four implicated officers have been convicted of murder.
