A service has been scheduled for one of two teenagers found shot to death behind a grocery store in an Atlanta suburb.

H.M. Patterson & Son Funeral Directors says a memorial service is planned at 10 a.m. Friday at Roswell Presbyterian Church for 17-year-old Natalie Henderson.

Roswell police arrested 20-year-old Jeffrey A. Hazelwood on Wednesday on two counts of murder in the deaths of Henderson and 17-year-old Carter Davis. Both were found Monday with single gunshot wounds to their heads.

Police have not released a motive in the deaths.

Henderson would have been a senior this year at Roswell High School.

Davis, who lived in Rapid City, South Dakota, during part of his high school years, was about to start his senior year at River Ridge High School in Woodstock.
