Former journalist Joel Palacios was among five persons killed by a man who went on a stabbing rampage after quarreling with his girlfriend at Central Park Condominium in Pasay City Tuesday night.

The assailant, Alberto Garan, 39, first stabbed his girlfriend Emelyn Sagun, 30, with whom he had a heated argument at 6 p.m. on the 14th floor. Investigators said Garan was jealous of a man who was always with Sagun.
