The killings of two 17-year-olds behind a supermarket Aug. 1 left the Roswell community heartbroken — and mystified.

Why did Natalie Henderson and Carter Davis both pull their cars behind the Publix store at 3 a.m. on a Monday? What was the connection, if any, between the two slain teens and Jeffrey Hazelwood, 20, who was later charged in their murders? What was the connection between the two teenagers themselves?

The double homicide of teenagers is unprecedented in Roswell, and the city police have been treating it like few other cases. Although investigators made an arrest within 48 hours, they have released few of the key details of the crime to the public.

That is likely to change in a Fulton County courtroom on Friday morning. There, at a probable cause hearing for Hazelwood, the state is expected to produce enough evidence to show why the case against Hazelwood should proceed to the grand jury.
