A US woman has said she was panicked but as calm as possible before a New Mexico emergency call handler hung up on her while she tried to save the life of a friend who had been shot.
Esperanza Quintero said that she wished 911 dispatcher Matthew Sanchez had done more to help before telling the 17-year-old to "deal with it yourself".
In the recording, the caller snaps at Mr Sanchez for repeatedly asking whether Jaydon Chavez-Silver is breathing.
The call was made after 17-year-old Jaydon was shot in June as he watched other teenagers play cards at a friend's house. He later died.
City officials said Mr Sanchez resigned on Tuesday, a day after a recording of the 911 call was released.
