WATCH: How Pastillas Girl's mom Teresa Yap was killed [video]

Teresa Yap, mom of Pastillas Girl Angelica Jane Yap, was shot dead by a gunman Sunday night in Caloocan. Watch how she was killed in this video.

The uploader said in the description that the raw video captured by Barangay 131's closed-circuit television (CCTV) camera was edited to make it less graphic.

According to news reports, Teresa Yap was about to dine at a roadside eatery along Tagaytay Street together with the sibling of Pastillas Girl and a niece when a man suddenly approached and shot her at close range.

The victim sustained a gunshot wound in the back of the head. She was immediately brought to a hospital but was pronounced dead at 9:20 p.m.

Pastillas Girl was shocked when she went to the hospital after learning about the incident.

Teresa Yap has received death threats prior to the crime. She would be eliminated before Christmas day, one of the text messages allegedly stated. A relative told reporters that the mother of Pastillas Girl didn't mind the threats.

Based on the video that captured how Pastillas Girl's mother was killed, the identified gunman was riding a motorcyle when he fled.
