Angleton police say James Harris, Jr. is in custody. They say he stabbed Alton and Darla Wilcox after breaking into their home on the afternoon of January 14.
Alton Wilcox, 85, died at a hospital. His wife Darla Wilcox, 69, is recovering at the hospital.
According to police, Harris robbed the couple to get rent money for his south side hotel room. Police say the charges could be upgraded to capital murder later this week.
Bond is set at $1 million total for the two charges.
