(CBS) OKLAHOMA CITY - A witness' 911 call following the fatal shooting of Christopher Lane, an Australian baseball player who had been attending school in Oklahoma, was released Wednesday. Police say the 22-year-old was killed Friday by three "bored" teenagers who decided to kill someone for fun.
"There's a young man he just fell over in a ditch and he's got blood on him...," the woman on the 911 call who identified herself as Joyce Smith said.
"He's got blood on his back," she told the 911 operator.
In the background of the call a man can be heard advising the woman that the man had been shot.
"He said he heard the shot and he knows what the car looks like," Smith said of the other witness.
Smith went on to tell the 911 operator that the victim was turning blue and making a 'huh, huh, huh' sound. She described him as being unconscious and barely breathing.
Repeatedly throughout the call Smith advised the operator she didn't hear any sirens.
"I hear no sirens, I see no lights," she said about 5 minutes and 50 seconds into the call.
About six minutes into the call she said she saw lights.
"If you don't hurry, he's gone," Smith said.
The 911 operator assured her that an ambulance and police officers were on their way. The operator asked Smith whether the victim was still breathing.
"He's stopped breathing," Smith responded.
Seven minutes into the 911 call police arrived and Smith asked whether it was OK to hang up the phone.
Police Chief Danny Ford said Monday that Lane, who was visiting the town of Duncan, where his girlfriend and her family live, had passed a home where three boys were staying and that apparently led to him being gunned down at random.
Prosecutors charged 15-year-old James Francis Edwards Jr. and 16-year-old Chancey Allen Luna with first-degree murder on Tuesday. Police say the two killed Lane to overcome boredom. Under Oklahoma law, anyone who is 15 or older and facing a first-degree murder charge is automatically tried in adult court.
Also Tuesday, 17-year-old Michael Dewayne Jones was charged with being an accessory after the fact and with using a vehicle during the discharge of weapon. Jones is charged as a youthful offender but will still have his case heard in adult court.
No bond was set for the younger boys. Bond was set at $1 million for Jones.
Ford said a 17-year-old defendant, Jones, told officers that the three teenagers were bored and shot Lane for "the fun of it."
"They saw Christopher go by, and one of them said: 'There's our target,'" Ford said. "The boy who has talked to us said, 'We were bored and didn't have anything to do, so we decided to kill somebody.'"
He said they followed the 22-year-old Lane, a student from Melbourne attending college on a baseball scholarship, in a car and shot him in the back before driving off.
One of the suspect's mothers told CBS affiliate KWTV in Oklahoma City her son and his friends were in a "wannabe gang." Police told KWTV the suspects may have killed an animal prior to shooting Lane, and that they planned on killing more people.
