After Hupp’s plea to murder on Wednesday in the 2016 fatal shooting of mentally disabled man, Lincoln County prosecutors reopened the investigation of the fatal stabbing of Hupp’s friend, Elizabeth ‘Betsy’ Faria.
Hupp, who will serve life in prison without parole for fatally shooting a man in O’Fallon, Mo., in 2016, had an earlier target who got away, prosecutors have said.
“Hupp has done nothing but cause heartbreak and grief to so many families,” said Gumpenberger’s half-sister, Krystal Conn, calling Hupp a “monster,” “disgusting” and a “serial killer.”
