ST. PAUL, Minn. (AP) - Four people have been charged in the death of a Minnetonka High School student during an alleged robbery in St. Paul.

Ramsey County prosecutors say 16-year-old Samantha Burnette was fatally shot after fighting back when her sister was pistol-whipped in an alley Sunday. The prosecutors have accused a 29-year-old woman of arranging her ex-boyfriend to rob her friends.

The suspects charged Tuesday in the incident are Kalisa Chardale Smith, who was friends with Burnette's sister; Smith's ex-boyfriend, Christopher Rayshawn Calloway; and Calloway's friends, Davonte Bobo and Vincent Harris. They're each charged with two counts of second-degree murder and one count of aggravated robbery.

It wasn't immediately clear if the suspects have attorneys.

Burnette lived with her grandmother in Minnetonka and was spending the weekend with her mother and sister, who are St. Paul residents.
