[1] Soerjo and two policemen were captured by pro-communist (PKI) troop at Walikukun, Widodaren, Ngawi on 9 November 1948, and their dead bodies were found afterwards.

Suryo also had the opportunity to study at Politie-School (Police School) in Sukabumi, West Java and at Bestuursschool or Bestuurs Academie or Department of Home Affairs in Batavia (Jakarta).

Responding to this ultimatum, Sukarno left the decision entirely in the hands of the East Java government, namely to refuse or surrender.

Suryo and two other passengers, namely Colonel Duryat and Major Suroko, were ordered to get out of the car, taken to the forest, and then killed by the pro-PKI troops.

[4] Soerjo was buried in the Sasono Mulyo, a monument built to commemorate his services which is located in Kedunggalar, Ngawi.
