Fresno police officers say so far they've been successful.
"Of the four suspects, we have one in custody right now, and we're looking for the other three. We have tactical resources from the city and we'll be looking for those three throughout the day and night," said Lt. Mark Salazar with the Fresno Police Department.
The murder on March 8th was Fresno's 12th murder of 2010. Since then there have been two other homicides in Fresno.
