Tip calls from an unlikely source may have put an end to a series of Sioux Falls robberies.
Twenty-one-year-old Domach Khai appeared in court Monday and was charged with five counts of armed robbery.
The crimes occurred between November 11, 2012 and one week ago Monday. And what makes this case unique is that he's the one who gave police the most incriminating information.
Here's how it unfolded.
Shortly after police released surveillance photos of the man who held up the Casey's at 15th Street and Sycamore Avenue, an anonymous caller gave police information about the robbery.
On Christmas Day, a man matching the description held up a Get N' Go on east Arrowhead Parkway. Two days later, police received another tip from a man who sounded a lot like the first caller.
And last Monday, police received a third call following the BP robbery at 18th and Cleveland. In each case, the call came in from a blocked phone number. Police became suspicious because the man on the phone knew things about the robberies they hadn't released to the public. When the caller suggested the suspect was about to leave town, police stepped up their search.
Police subpoenaed phone company records to find Khai at this house at 807 South Cleveland Avenue. After a search warrant was issued, they also found two cash drawers and a butcher knife. A red ball cap, like the one worn during one of the robberies, was also found in Khai's home.
Gary Cone, the owner and man behind the counter when the BP station was robbed is glad to hear of an arrest.
"All the people around out neighborhood are kind of like a big family and they are really relieved to know they've caught this gentleman or whatever he is that's running around robbing people," Cone said.
With Khai in custody, police are cross-checking evidence from this set of robberies to see if there are links to other unsolved ones in the area.
"It's always a little bit easier once you have a known suspect that has committed some other robberies to be able to compare the different crimes and see if they are responsible for that," Sioux Falls public information officer Sam Clemens said.
Khai was officially charged with five counts of first degree robbery in court Monday afternoon. Bond was set at $50,000 and he was ordered to have no contact with any of the convenience stores he is accused of holding up.
