The author of the Saint-Louis massacre was armed with 600 bullets

A 19-year-old gunman was shot dead by police on Monday after killing a sports teacher and a 16-year-old girl and wounding seven others. The young man was armed with an AR-15 semi-automatic rifle and had several magazines strapped to his chest in addition to the ones he kept in his bag.

“It appears he entered the building with over 600 rounds of ammunition,” local police chief Mike Sack said at a press conference on Tuesday. Mike Sack said the response of police officers, who said they arrived on the scene four minutes after the emergency call, was able to avert an even more “horrendous” tragedy.

A letter found by police in the shooter’s car sets out his motivations for the attack. “I have no friends. I have no family. I have never had a girlfriend. I have never had a social life. I have been lonely and isolated all my life,” she wrote.

On Tuesday, Joe Biden offered his thoughts and those of his wife, Jill, “to all the victims of the senseless shooting in St. Louis.” “As we mourn high school shootings, we must take action, starting with banning assault rifles,” Trump tweeted.

School shootings in particular are an atrocity in America. In May, a teenager killed 19 schoolchildren and two female teachers at an elementary school in Uvalde, Texas. On February 14, 2018, a massacre at a high school in Parkland, Florida sparked a broad national movement led by young people demanding stricter controls on personal weapons in the country.

Banned in 1994 along with other semiautomatic rifles, the AR-15 was reauthorized in 2004 and has since been the center of controversy for its use in several shootings, including Uvalde and Parkland.
