The photo of her tattoo which she posted on social media was one of the key pieces of evidence which led Calamba policemen to arrest Annshiela Montes Belarmino, the suspect in the stabbing to death of part-time driver Jang Lucero last week.
According to John Consulta's report on "24 Oras", Belarmino was the ex-girlfriend of Lucero's present partner.
Belarmino was also seen in a relevant CCTV footage taken before Lucero was killed.
An investigator said Belarminno was identified because of her hair and the tattoo on her back. Aside from the pictures on social media, the authorities also took a photo of the tattoo.
"Si Anne ay allegedly may konting selos dun sa biktima. Siya mismo yung sumakay sa saksakyan ng biktima and napaka-importante na na-identify siya dahil siya mismo yung kasama nung mga sumaksak sa biktima," said a police official. -NB, GMA News
