Helen and Olga are kindly old ladies who open their hearts and wallets to down-and-out men in Los Angeles. In a city named for angels, the two women seem heaven-sent. After one of the men is killed by a hit-and-run driver -- and then another suffers the same fate -- investigators uncover a horrifying and twisted plot that stuns even the most seasoned detectives. All six episodes of this chilling podcast from Keith Morrison and Dateline are available now.
