The parents of a 5-year-old killed in last week’s elementary school shooting in Bend, Oregon, have hired attorneys to investigate the incident. The family says it wants to determine whether the shooting could have been prevented and to examine how the teenage suspect obtained the gun.

Reports note that the parents are focusing on both school-related and gun-purchase aspects. According to outlets, they are probing the school’s safety plans and protocols, including what measures were in place and how they were followed. They are also investigating the circumstances around the weapon’s acquisition by the teenage gunman.

While coverage is consistent on the family’s hiring of legal support and the areas of inquiry, it differs slightly in wording and emphasis. The Oregonian reports the family has engaged multiple law firms, while other outlets describe the matter more generally as an investigation into school planning and the gun purchase.
