What would drive a woman to kill her family and herself?

HOUSTON — Questions continue to surround a recent tragedy at the San Luis Resort on Galveston Island, where a woman killed her husband and two sons before fatally shooting herself.

Did depression drive Flor Pineda, a seemingly happy mother two, to commit such a horrible act? Were there signs beforehand? If there were signs, could anything have been done to prevent it?

The impact of what happened at the beach resort reaches far across the city.

Goose Creek ISD in Baytown, where the young boys attended school, has counselors on hand for both students and faculty close to the family.

Meanwhile, Galveston police continue to search for a motive and answer one question: why.
