Shaina Foster, 17, was tried as an adult and sentenced to five years in prison after a Manhattan judge found her guilty of tying up and robbing retired lawyer Paul Aronson. Foster met the 85-year-old man on the dating website seekingarrangement.com, which encourages users to "find your sugar baby." 

Foster arrived to Aronson's Murray Hill home with her sister Shalaine, and the teen told investigators that she became uncomfortable after the "ugly, old and disgusting" Aronson made an unknown request. 

Shaina stated that "[Aronson] was starting to creep me out," so "I tied him up. I took his money and I left." The teens then went shopping for makeup after making off with $420 and Aronson's credit cards. 

The other sister copped a plea deal and was sentenced up to four years in prison after being tried as a youthful offender, which means that her records will be sealed.
