She was bleeding that night after that knife injury, so even if she wears glove there might be blood traces. Also her stiletto's prints would be there. And her bridal dress she was wearing it's tiny bits might have been found. It is too heavy dress to wear and kill anyone 😆
I also love to see that Maya is not the killer..but it is no harm to kill a man like Ashwin..If Maya kills no harm there...There was no finger print on the syringe by which Ashwin is killed..Maya is so smart that she made sure that no fingerprints by wearing gloves etc..it can be possible..Maya executes things perfectly..
