Twenty-three-year-old Megan Boken was murdered in August 2012 while in St. Louis. She was on the phone with her mom when authorities say 19-year-old Keith Esters stole her phone and shot her. Prosecutors say Esters wanted to sell the phone.
Boken's father and sister asked lawmakers Monday for more security features on smart phones so they're worthless to thieves.
"It is very important to understand that what happened to Megan can happened to anyone, and it needs to be ended," said Paul Boken.
Last week, Jason Knowles and the ABC7 I-Team followed the trail of stolen smartphones in Chicago and found that 90 percent of them are being sold in Hong Kong, for up to $2,000 each.
Others are being traded in or sold at local, independent wireless stores.
