GREEN RIVER, Wyo. (AP) — A 68-year-old Wyoming man has pleaded not guilty to two counts of aggravated vehicular homicide in the deaths of a 62-year-old woman and her great-granddaughter.

George Maestas also pleaded not guilty Friday to a charge of driving under in the influence of a controlled substance causing serious bodily injury.

Prosecutors say Maestas had taken narcotics before striking a house in Green River on March 10, killing Debra Devries and 1-year-old Stella Doak.

District Court Judge Nena James set Maestas' trial for July 10. He remains jailed with his bail set at $1 million.

Defense attorney Stan Cannon said he would address the issue of Maestas' bail after he receives the results of blood tests, including tests to determine whether Maestas may have suffered a stroke or other medical issue.
