Authorities are investigating if a 64-year-old man charged with murdering two women in the 1980s in California may also have committed crimes in North Texas, according to a report.

Last month, Horace Vaultz Jr. was charged with two counts of murder and the special allegations of multiple murders, commission of the crimes during a rape and sodomy, and lying in wait, according to the Burbank Police Department.

He is accused of the July 16, 1981, killing of 20-year-old Selena Keough, whose body was found in Montclair in San Bernardino County. He is also accused of the June 9, 1986, killing of 22-year-old Mary Duggan, whose body was found in a car in Burbank.

Investigators are now probing Vaultz’s time in Texas -- records show he lived in the Denton County city of Justin, and he may have been in Fort Worth after 2012, Fox 4 reported.

Vaultz is being held without bail, and he’s awaiting a death penalty trial.

Los Angeles County prosecutors said the case is the first in the county resulting from the use of investigative genetic genealogy.
