ST. PAUL, Minn. (AP) — St. Paul police say a young homicide victim had answered an ad for a cellphone on Craigslist and was fatally shot by the purported seller.

Family members say 19-year-old Aung Thu Bo and his girlfriend met the seller in a public place last Friday afternoon to buy a smartphone. The man asked them to drive him to his house to get the phone. Bo’s mother, Than Than Aye Bo, says they drove about a block, the man demanded Bo’s wallet and shot him in the head. His girlfriend was unharmed.

Family members say Bo was removed from life support Saturday at Regions Hospital. Relatives say Bo was a computer engineering student at Hamline University and worked two jobs to support his family.
