Gonzalo Lopez who's responsible? #CollinsFamily #Escapedprisoner #TexasCorrections #RobertHurstNew details have emerged revealing how convicted murderer Gonzalo Lopez escaped a prisoner bus in Texas and what he did before killing a family of five, police say. Lopez's escape last month triggered one of the largest inmate search efforts in state history as hundreds of officers scoured the wooded area where he was believed to have been hiding. Authorities say the fugitive killed a family in their Leon County home last week, and he later died in a shootout with police. Just days before he killed 66-year-old Mark Collins and his four grandsons, Lopez broke into a neighboring property, according to spokesman Robert Hurst of the Texas Department of Criminal Justice. Collins and his grandchildren had been visiting the family's weekend ranch outside Centerville, Texas, located near where the inmate had escaped three weeks prior and within the perimeter police were searching following the escape, according to the Texas Department of Public Safety. Lopez broke into the neighboring home of the sprawling Collins ranch property "24-48 hours in advance" of his attack on the family, Hurst said. No one was home at the neighboring house at the time. Law enforcement officials did not appear to alert residents that there were signs of suspicious activity at the home next to the ranch, according to CNN conversations with local residents. In response to questions about why locals were not alerted as soon as law enforcement suspected a break-in had taken place, a Texas prison spokesman said DNA testing was needed to confirm it was Lopez who broke into the home.
