The FBI has taken over the investigation of the Boston Marathon bombings that killed three people and left more than 100 others injured, officials announced Monday evening. Boston police commissioner Ed Davis confirmed the latest death toll in a press conference, but denied reports that police were holding a suspect in a local hospital.
"We will turn every rock over to find the people who are responsible for this," Davis said.
"There's been a horrendous loss of life," he added. "At least three people have died in this event. But the number of injuries and the people injured is an unfolding issue right now. We will not have hard figures on that until [Tuesday] morning."
Davis made a point to dispute reports that a suspect was in custody. "I want to stress one thing: there is no suspect at Brigham and Women's Hospital," he said. "There are people that we are talking to, but there is no suspect at Brigham and Women's hospital as has been widely reported in the press. I'd like to fix that right now."
FBI Special Agent-in-Charge Rick DesLauriers said it is a criminal investigation with the potential to be a terrorist investigation. Massachusetts Governor Deval Patrick said there will be increased security checks and heightened law enforcement in the coming days, and that the measures will remain as the investigation continues.
"The city of Boston is open and will be open tomorrow, but it will not be business as usual. There will be a heightened law enforcement presence consistent with the severity and seriousness of the ongoing investigation," Patrick said.
Officials will hold another press conference on Tuesday at 9:30 a.m. ET.
