UPDATE 5:13 p.m.: Kinesiology Professor Steven Loy is safe. Loy sent an email to staff members of the kinesiology department stating that he and his daughter, who also ran the marathon, and his family members who were spectating nearby were all safe.

“Our family saw things they should not have seen.  It was too close… and we were very lucky,” Loy said in the email. “Others were not.  It’s scary.”

He was not close to the finish line at the time of the explosions, but members of his family who watched from the sidelines were nearby.

“My family was across the street from the explosion and gave some of (their) clothes to cover the injured,” Loy said.

Cellular service was shut off in fear of triggering additional explosive devices.

“For a time, the six members of my family were separated and phone contact was impossible,” Loy said.

The death toll rose to at least three people, and more than 130 people were injured.

UPDATE 2 p.m: A third explosion occurred at the JFK Library according to the Associated Press.
