Off-Duty Officer Detains Suspect After Fatal Stabbing at Londrina Gym

Overview

• Security footage shows the attacker waiting in the parking lot, approaching from behind and stabbing David Schmidt Prado five times as he tried to flee into the facility.
• Prado, 37, died despite emergency care; he worked in the administrative sector of a fuel-station network in Londrina.
• Police identified Lucas Wancler Ferreira dos Santos as the suspect, arrested him in flagrante on a qualified-homicide allegation, and said he remained silent during initial questioning.
• An off-duty military police officer training at the gym restrained the suspect; in testimony the officer said he initially thought it was a robbery and that the suspect stated the victim had "messed with my woman."
• The gym closed temporarily and reported cooperating with authorities; the funeral was held Wednesday in Cornélio Procópio, and reports say the victim left a six-year-old son.
