Robredo wanted to watch the closing ceremonies of the Palarong Panglungsod, where his youngest daughter, Jillian, won a swimming event.
Bongat told dzMM Robredo was advised by his wife, Atty. Leni, not to rush anymore for the ceremony since he might not make it on time.
Robredo, however, decided to still take the private plane, which crashed into the sea near barangay Ibingay in Masbate around 4:30 p.m. on Saturday.
A search and rescue operation for Robredo and 2 pilots was still ongoing as of posting time.
Robredo was in Cebu for a Criminal Investigation and Detection Group (CIDG) summit.
Robredo's family lives in Naga City, where he served as mayor for many years. He won a Ramon Magsaysay award in 2000, Asia's equivalent of the Nobel Prize, for his governance of the city.
