NEW MADRID, Mo. -- A 21-year-old man is jailed without bond after being accused in the shooting death of a convenience-store clerk in his Southeast Missouri hometown.

New Madrid County prosecutors have charged Deion Martin of Parma, Missouri, with one count each of first-degree murder and first-degree robbery and two counts of armed criminal action.

Investigators allege Martin shot 59-year-old Brenda Smith in the head May 18 at the D and L One Stop in Parma when she refused to open the store's safe. Smith later died at a hospital.

Martin was arrested Sunday in the St. Louis area after police said they got a tip about his whereabouts.

Online court records don't show whether Martin has an attorney to speak on his behalf. Martin does not have a listed home telephone number.
