(AP) – The suspect in an armed robbery Tuesday afternoon in Rapid City took his own life a few hours later during a standoff with police in Custer.

Medina says a witness gave police the pickup’s description and license plate number, leading to it being spotted by police north of Custer. A brief chase into Custer followed, leading to a standoff that ended about 7:30 when the man commited suicide.
