Known primarily for his work on scoops about criminal activities, he first anchored the newscast News TV Quick Response Team in 2018 before co-hosting the magazine show Dapat Alam Mo!

In 2023, Sumangil joined the newscast 24 Oras as a regular anchor and had his own investigative public service show, Resibo: Walang Lusot ang May Atraso.

[1][2][3] He eventually reassigned to a field journalist covering criminal activities exclusively,[4][5] drawing inspiration from then-GMA Integrated News reporter Michael Fajatin.

[1] Sumangil's scoops particularly included the newscast 24 Oras's "Justiis: Condominium Behind Bars", which focused on Santa Rosa City District Jail's crowds.

[2] During Enriquez's medical leave before his death, Sumangil temporarily worked on the newscast,[16] and thought that this could prepare him for an opportunity to pursue it permanently.
