Police opened a homicide investigation Saturday after discovering the bodies of seven people in a Georgia trailer park, the latest multiple killing to hit the United States. 'There are seven people deceased and two people critically injured,' Candice Temple, a spokeswoman for Glynn County Police Department, told selfnews. 'The county coroner is working to identify the victims.' Lieutenant David O'Neal of the Glynn County department said police 'received a 911 call shortly after 8:00 am (1200 GMT) of multiple deceased persons found in a mobile home in the New Hope mobile park.' 'Officers responded and upon entry found multiple persons deceased and two persons critically injured,' he told selfnews. But there were no immediate details on how the seven people died, or the chain of events in the trailer park in Brunswick, Georgia, about 70 miles (113 kilometers) south of Savannah. 'The investigation is a homicide investigation,' O'Neal said. 'The coroner pronounced the victims deceased at 10:30 am (1430 GMT).' He declined to specify whether the victims had been shot, adding the two wounded people were transported to a local hospital. A press release from the police department said some victims had been tentatively identified, but that officials would not release any details until the victim's families had been informed. The killing at the New Hope trailer park, which is described on its website as a 250 acre site of pine trees and pecan groves, is the latest in a spate of mass killings in the United States. In August, a Pennsylvania man embittered by what he described as constant rejection by women, walked into a gym and opened fire on a dance class killing three women before turning the gun on himself. In a blog uncovered after the murders, he documented in chilling detail his plans to carry out the shooting, and even described him carrying out a trial run of the killings. Earlier, in April, a spate of mass shootings horrified Americans. On April 3, Jiverly Voong barricaded a civic center in upstate New York, killing 13 people, most of them recent immigrants, before shooting himself. Days later, a Washington state man shot and killed his five children, between the ages of seven and 16, then turned the gun on himself after his wife told him she was leaving him. Then on April 7, a gunman shot dead his wife, daughter and two other people before killing himself in Greenhill, Alabama.
