An ex-physician has been charged with capital murder in the February death of a woman who was left incapacitated in 1988 after being strangled and sexually assaulted in a case that went cold, Dallas prosecutors said.
George Guo, a registered sex offender who spent more than a decade in prison, was arrested Wednesday in Houston in connection to the June 1988 attack on Dr. Katherine Bascone, according to the Dallas County District Attorney’s Office.
The 56-year-old was being held Thursday on a $5 million bond in the Dallas County jail.
Bascone suffered a brain injury because of the strangulation, leaving her blind and needing lifetime care.

She died in February, and a medical examiner ruled her death a homicide.
Authorities said DNA testing was part of the investigation, though details about when and how Guo was linked to the case haven’t been released.
The district attorney’s office said it worked with authorities in Highland Park, the wealthy Dallas enclave where Bascone was attacked three decades ago.
Guo was convicted in 1991 for burglary of a habitation after breaking into the apartment of a Southern Methodist University student.
Authorities broke down the apartment door and caught Guo with condoms, a ski mask, military tear gas and syringes filled with sedatives, according to prosecutors.
Guo also was convicted of burglary of a habitation with intent to commit sexual assault in a 1999 incident in which he was caught breaking into a girl’s residence, the district attorney’s office said in a statement.
He was sentenced to 14 years in prison in that case. He was released in 2013.
Online records don’t list an attorney representing Guo.
