( CNN ) -- A man suspected in the deaths of three people in Panama is now wanted in the slaying of an American woman whose body was found last week , Panama 's national police said Saturday . The body of Cher Hughes , a native of suburban St. Louis , Missouri , was found Tuesday on the property of William Adolfo Cortez Reese , who is suspected in her death , said Javier Carrillo , director of the national police investigation unit . Carrillo said Cortez and his wife , Jane , are on the run . Cortez `` may be from Holland . We 're not sure that 's his real identity , '' he said . `` We found a false passport . '' He said Panamanian authorities are attempting to reach police in Holland . Hughes , who was in her early 50s , was identified by her husband , Keith Werle , who lives in Panama . A second body -- which has not yet been officially identified -- was found near Hughes . `` We believe the motive is that he ( William Cortez ) is killing people to take their property , '' Carrillo said . He added that authorities do not know Cortez 's whereabouts , and have not received any tips from the public . Werle said he was on Cortez 's property , a massive piece of farmland on the island of Isla Colon in the western province of Boca del Toro , as police executed a search warrant . He said his dog led authorities to a shallow grave , where they found Hughes ' body . Dwayne Cooney , a family friend , said Hughes had lived in Panama for the past decade and owned a hotel , the Casa del Sapo , in Boca del Torro . He described Hughes and Cortez as friends and neighbors . Hughes had lived in St. Petersburg , Florida , where she owned a neon sign business , before moving to Panama , Cooney said .
