A La Crosse man acquitted in a fatal stabbing at a downtown gas station faces new charges that accuse him of threatening to kill his father. 

Mitrel Anderson’s father told La Crosse police his son on Wednesday also threatened to have “his guys” kill him, according to reports. Anderson “has not been right” since he “had to kill his friend in self-defense,” his father told police.

A jury in December 2014 acquitted Anderson of homicide in the June 2, 2013, death of DeMario Lee inside the men’s restroom at the Cass Street Kwik Trip, after finding he stabbed Lee in self-defense after a confrontation.

Anderson testified that Lee ambushed, beat and threatened to kill him before Anderson drew his knife and swung at Lee’s head; prosecutors argued that Lee, 24, of Illinois was stabbed as he was leaving the restroom and that Anderson wasn’t justified in using deadly force.

Anderson’s father said the incident left him “possibly unstable,” with his son resorting to alcohol and drug use, reports stated. He said Anderson is violent and possibly armed.

Anderson’s father’s roommate kept the two separated during an argument before Anderson threatened to “put him in the hospital,” according to reports.

Police arrested Anderson, 27, about 1 a.m. Saturday at The Library bar in downtown La Crosse for two counts of disorderly conduct and bail jumping. Anderson told police his father lied about the threats. He will appear in La Crosse County Circuit Court at a later date.
