Timothy Howard Virts and his daughter Caitlyn Marie Virts have been found and an Amber Alert canceled, according to Baltimore County police and fire officials.
They were located at a motel in Florence, S.C. Caitlyn appears to be unharmed, and her father is in police custody.
Caitlyn, 11, had last been seen around 7 a.m. Thursday in Dundalk, Md.
Police announced Friday that they have obtained a warrant charging Timothy Virts with murder after finding 36-year-old Bobbie Jo Cortez dead inside her Dundalk home a day earlier.
Investigators believe expanding the Amber Alert nationally, including digital billboards, led to Caitlyn being found.
Investigators say Cortez lived in the home with her three children -- Caitlyn, Caitlyn's twin sister and a son -- and two other adults. For the past several weeks, the victim had also allowed 38-year-old Timothy Virts to live in the home, police said.

Someone in the home noticed Caitlyn and Timothy were missing after finding the body; the Amber Alert was issued at 10:46 a.m. Thursday.
Police were looking for a 1999 black Dodge Durango with Maryland license plates 5AJ4458 that authorities said was registered to Cortez's husband, Daniel Williams Cotez, who is being held at the Baltimore County Detention Center on various sex offense charges.
Caitlyn will be returned home as soon as possible, police said. Detectives are on their way to South Carolina.
Timothy Virts' return is pending extradition.
