WEST FARGO (AP) - An 18-year-old West Fargo man has been charged with attempted murder for allegedly stabbing a 21-year-old Fargo man in the chest in August.

LaSamuel Richardson III is accused of stabbing Andrew Gregerson with a 7-inch kitchen knife.

Court documents say the stabbing occurred in a mobile home park during a fight involving several people. Three other people have been charged with felony conspiracy in the case.

Richardson earlier this month began serving a five-year prison sentence for a chase in Moorhead, Minn., that occurred two weeks after the alleged stabbing.
