Only two months at work, the Pakistani haris or watchman of the building of Lenlie Oliverio had an argument with her that day over accidentally spilling the bucket of water he was using for cleaning. After a heated confrontation, the Pakistani knocked on Lenlie's room pretending there was a Fire Alarm problem, then when she opened the door, he stabbed her to death.
Note that the haris or caretaker was only two months in the country and 10 days in his new work or building under his watch. Lesson: don't engage in heated argument with anyone while you're abroad, and don't let anyone in inside your flat or room especially if you are alone.
He had only started working at the victim’s building 10 days before the crime.
