Free attacker stabs grandmother to death after night of partying

A young man stabbed his own grandmother to death. The crime occurred after a night of partying, when the aggressor was on the loose. There were already complaints of domestic violence crimes against the young man, registered by both his ex-girlfriend and his mother. The aggressor's partner was also a victim of aggression, having been beaten and left mistreated. The case highlights the failures in the system protecting domestic violence victims, which did not prevent the aggressor from remaining free and committing the murder.
