what is this episod

RIP Chris Benoit
they where on the marrathon today(i never watched the show until today i was at my grandpas house and he watches this show but i fell asleep during these 2 episods)



the first 1 i want to know:a chineese girl goes missing after she misses a date with her boyfriend and she met him on online dating and the boyfreind says' sometimes people do things that come to haunt them'' and also her family has a deli and she and her brother got robbed at gun point



2: all i remember

1 of them got killed and the murders took someones finger and i think it was in mexico

and the murders whore masks that looked like skullls
