I know most alumni (especially those in the economic/banking/finance sectors) are familiar with the name. He was an Atenean and used to be Urban Bank's president sometime in the 90s.
He committed suicide in the Loyola Memorial Park in Marikina, leaving his wife and several Atenean children behind.
Let us just pray for Mr. Borlongan's soul and offer our condolences to his family to be strong in this dark hour.
