Guam - As thousands of island residents observed Palm Sunday, several families were mourning the loss of their loved ones involved a fatal crash that occurred in Yigo.

"Given the amount of damage to both vehicles one would assume that the vehicle was traveling pretty quick," explained Officer AJ Balajadia, spokesman for the Guam Police Department.  Mangled metal is all that's left of two cars involved in fatal crash that occurred just after one1pm Sunday along the Back Road to Andersen. Officer Balajadia said, "You have a 2003 silver Silverado traveling south on Route 15 lost control ran off the roadway entered back on the roadway and encroached into the north bound lane striking or colliding with a 2009 Toyota Corolla."

The head on collision left four people dead and one another person recovering at the Guam Memorial Hospital. "Right now the information is still sketchy we're still trying to determine who was in what vehicle. From what we understand three people were in the corolla and two were in the truck," he said.

GPD's Highway Patrol is also investigating whether speed or alcohol were contributing factors. "We're of course any time there's a fatality we look at speed alcohol and other conditions to help determine what may have been the cause for this crash. Given the amount of damage to both vehicles one would assume that the vehicle was traveling pretty quick," he said.

GPD is waiting for families to come forward to identify the victims in the crash. Their deaths mark the fourth, fifth, sixth and seventh traffic fatalities of the year. In the meantime there were physicians from Naval Hospital that were in the area during the time of the crash that assisted GFD medics and police.

"We're really grateful for that to be able to have that connection with the military and our local community," Balajadia said. "It doesn't matter whether or not they're on base or off base they stepped up and we really appreciate that and they should be recognized."
