Man kills woman, then himself in front of son

The Associated Press

TAMPA, Fla. -- Authorities say a man fatally shot a woman in front of their 8-year-old son and then killed himself in the parking lot of a Tampa restaurant.

The Hillsborough County Sheriff's Office reports that 38-year-old Guillermo Garcia and 33-year-old Okariny Diaz had met outside the Village Inn Friday so Garcia could turn his 8-year-old son over to the boy's mother. Garcia and the boy had driven up from Broward County that morning.

Witnesses say the two parents got into an argument, which led to Garcia shooting Diaz several times and then turning the gun on himself. Both were pronounced dead at the scene.

Several adults and a 10-year-old girl had been with Diaz to pick up her son and witnessed the shooting. No other injuries were immediately reported.
