Four children found dead with their grandfather in Texas have been identified.

The grandfather was identified as Mark Collins, 66, according to Fox 26 Houston. Authorities believe the five family members were murdered by prison escapee Gonzalo Lopez.

Lopez, an inmate convicted of capital murder, escaped custody on May 12 in Leon County. His disappearance sparked an intense manhunt throughout the area.

The relatives called local authorities to check on Collins, and officials found the grandfather dead, along with four grandchildren. The scene was an apparent murder.
