Another man, 27-year-old John Paul Lopez, who was said to have been employed by Bae as his house caretaker, was later arrested for assisting the gunman during the shooting by reloading his pistol magazine.

He then proceeded to a nearby alley and went inside houses, shooting at every person he encountered, including a pregnant woman named Rhea de Vera, who was shot in the stomach, and her 3-year-old daughter John Monica.

Lopez, on the other hand, disappeared after the shooting, and a reward of ₱100,000 was offered for information that would lead to his arrest, though he eventually surrendered himself to police and was taken into custody.

[8] Among those wounded were: Baby Anolacion, 33, Emelinda Aquipel y De Vella, 41, Enrique Aquipel, Cheveri Jaminal Ayson, Jemerlen Ayson, 46, Dovie Cabrera y Magsino, 66, Ken Cedric Caimol, 3, Michelle Caimol, 2, Ricky Diola Dumip-ig, 17, Antonio Orio, 15, Maricel Pajal, 27, Raul Ravelo, 73 and Kevin Magarago Vallada, 6.

[citation needed] After Lopez had hinted to investigators that Bae had already killed other people in previous years and buried their bodies around his house, police searched the area and unearthed the skeletal remains of a human being.
