A man sought for questioning in the killings of a woman and her father last week is now accused of capital murder in their deaths, authorities said.

Investigators in Shelby County said they had obtained arrests warrants charging John Peyton Scott III, 41, of Helena in the deaths of Sharon Tarwater Whited, 40, and father Chester E. Tarwater Jr., 75.

Officers haven’t located Scott, who could be armed and should be considered dangerous, police said late Sunday in an announcement about the charges.

Whited and Tarwater were found dead in a home in the Birmingham suburb of Helena on Wednesday. Police have not said how they were killed, but they initially said Scott was wanted only for questioning.

Scott was in a relationship with Whited and lived with her in the house with other members of her family, authorities said.

Investigators didn’t say what evidence led them to obtain warrants against Scott. The murder counts were classified as capital offenses because more than one person was killed.
