Store Owner Reacts To Supsected Robber

Bookmark and Share

David Charles Mentzer is a little older than most would expect for a person accused of robbing five convenience stores.

It even has surprised Detective Sean Kooistra with the Sioux Falls Police Department.

“Just with my personal experience, or with what you hear about robbers, somebody that age typically doesn’t happen,” said Kooistra.

Police arrested the 60-year-old Tuesday after he attempted to rob the Kum and Go Convenience Store on Western Avenue for the second time. Mentzer is also accused of robbing another Kum & Go in Sioux Falls, plus the Lambo's Convenience Store on 49th Street twice, the first time leaving with more than $1,200.

Ron Lamberty, owner of Lambo's, says he doesn’t care how old the suspect is.

“Whether it's a 15-year-old or a 60-year-old, to the person who gets robbed, it doesn’t make any difference,” explained Lamberty.

Prosecutors say that Mentzer has admitted to all five robberies. In court, Mentzer explained that he was laid off from his job in April, but did not admit guilt to the judge.

“There's a lot of people down on their luck that don’t rob stores,” said Lamberty.

Lamberty believes his store learned from the first time they were robbed.

“The things that you try to do at a convenience store is try to make sure there is very little money on hand, so it’s not an attractive place to rob,” said Lamberty.

The second time around, the suspect only got away with about $200. Lamberty hopes the changes and a more vigilant staff will mean his store won't be a target of robbers going forward.
