SAN ANTONIO -- In light of the recent killings of two South Side children, Sen. Carlos Uresti held an emergency meeting Monday morning with case workers and other agencies to discuss child abuse and neglect issues in San Antonio.

Uresti has assembled a blue ribbon task force to look into Sariyah Garcia and Sebastian Lopez's deaths to find out what went wrong in their case and other cases.

"We all agree that this case did fall through the crack and the idea is to come together to find out what happened," Uresti said. "What went wrong? Not specifically in this case, but in the many cases that have occurred in the past."

Uresti said red flags were raised in Sariyah's and Sebastian's case before their deaths.

However, the two children were still found dead on March 6, buried underneath their home on West Winnipeg Street, and stuffed in black trash bags, Uresti said.

Uresti said the focus of the investigation must be to enhance child abuse prevention and accountability.

He said state employees need to be analyzed because they have an obligation to care for children.

Uresti said 95 percent of employees do a great job, but like in any agency, there's always 5 percent that don't.

Uresti said above all 19-year-old Valerie Lopez must be held accountable because she confessed to killing Sariyah and rolling over Sebastian.

Uresti is leading an investigation into Child Protective Services (CPS).

An inspector general will give his findings to the state Legislature.

Among those who attended the meeting were CPS officials.

CPS officials said part of the problem is that San Antonio has a trust issue when it comes to child abuse investigations.

"When children are involved it's crucial that we have the trust (and) cooperation of the entire community," CPS official Mary Walker said.

Walker said the agency is ready to cooperate with the inspector general.

She said while the recent deaths are a tragedy, the agency is saving and protecting children every day.
