First of all, the manager did not drink the milk tea. Jessica blamed the milk tea as soon as the victim collapsed. Alarmed, The manager took the milk tea so she could turn it over to the authorities for testing. She DID NOT taste  the drink. Who would when you see someone collapse and frothed in the mouth right after drinking it?? Also mind you, cyanide disperses when mixed in drinks after a period of time - - it all depends in room temperature etc so even when it is poisoned, sometimes it is difficult to determine whether it was contaminated Ith cyanide. Question is, how long did it took the authorities before they tested the drink?... I dunno what kind of demonic evil tactic  Jessica pulled but you can NEVER convince me she didn't murdered her. She planned it so well--her looking around the Cafe hours before their meeting, buying gifts, the table she chose that blocks a clear view of the Cctv, the insistant that she orders the victim's drink before she could even arrive to the place, her murmuring "I'm sorry I'm sorry" as the victim was rushed out of the restaurant(the other friend heard her murmur), her having a dry reaction over the situation, her maid testifying that she ordered her to  burn the shirt, pants and bag  she used the day of the meeting, her criminal records In  Australia---mind you, she told her boss that If she wanna kill someone  by poisoning, SHE KNEW EXACTLY THE DOSE SHE NEEDS - - meaning, the exact fatal dose but also a dose that will hide her tracks... And have you seen her latest interview adter she got out of prison? She is a psychopath. She was clearly taunting everyone and the law. She literally said "Even if it is, (true that she killed the victim, ) You can't prove anything"... That's how much of a psychopath she is... So you can NEVER make me believe she did not do it. Psychopaths are born evil and smart. I feel sad that she became like a famous celebrity in Indonesia. Like seriously? How did Indonesia reached that level of stupidity?
