Police in Santa Ana are having trouble getting interviews with friends of a 23-year-old woman who died last week after a fight outside a night club.

Only one of the eight people who were with Kim Pham the night she was beaten has given an interview to police, CBS reports.

Pham was killed in a brawl outside Santa Ana night club The Crosby last week. Two women have been arrested and police are looking for one more suspect. A defense attorney for one of the detained women has claimed that Pham threw a punch, starting a fight.

Local police say they fear their investigation is stalled because Vietnamese immigrants don't trust the government.
