Video: Mexico grenade attack victim tells his story
"And then I heard a thump. There was a patrol car parked in the street blocking the cars -- a transport patrol -- and I heard something hit the patrol car. I turned round to see and something rolled ... when it stopped I realized that it was a grenade."
Rafael Bucio, a 30-year-old car-parking attendant, was out with his wife and two small children in Morelia, Mexico, on Monday night enjoying Independence Day celebrations when two grenades went off.
Bucio's wife, Gloria Alvarez, 32, was holding their 3-month old son Uriel in her arms when the explosion happened. She died from her injuries in a public hospital. The baby somehow escaped unharmed.
Watch Bucio tell his story of that night in the video below.
Ken Ellingwood reports that three arrests were made in connection with the two bombs that went off in Morelia on Monday night, killing seven people and injuring more than a hundred. But federal authorities now say they have determined the arrestees were not involved.
