The motive remains unknown for the mass shooting along a Raleigh, North Carolina, nature trail that killed five people and injured two others even as police released a five-day report on the incident Thursday.
The suspect, 15-year-old Austin Thompson, was critically injured in the Oct. 13 shooting.

The suspect's 16-year-old brother, James Thompson, was among those killed, according to the Thompson family.
Raleigh police said in a new statement Thursday that there's no apparent connection between Austin Thompson and the other victims "other than they lived in the same neighborhood."
"We are overcome with grief for the innocent lives lost ... and we pray for everyone who was traumatized by these senseless acts of violence," the Thompson family said in a statement Tuesday.
"We have so many unanswered questions," the family said. "There were never any indications or warning signs that Austin was capable of doing anything like this."
