The incident occurred around 7 p.m. at the store at 5500 East Bannister Road reports KSHB41 NBC Action News.
The same clerk involved in Wednesday morning's incident reportedly became involved in a disturbance with a person inside the store- then the clerk Tasered and shot that person.
The shooting victim later died at a Metro hospital.
It hasn't been reported yet if that person was somehow personally involved with Wednesday morning's foiled robbery suspects or whether the victim was attempting another robbery- though the latter isn't indicated.
CORRECTION: KC-MO Police have NOT confirmed the identity of the store clerk involved in tonight's homicide.
It had been reported here earlier- based on the report on KSHB's Web page- that the same clerk involved in Wednesday morning's attempt was again involved tonight.
Their story was changed and I offer this correction as well.
