The politician’s farm is located about six miles (10km) from Yby Yaú, the site where the 11-year-old Argentine nationals were killed, according to Paraguayan newspaper ABC Color.
Mr Denis and a 21-year-old employee had gone out to visit part of the farm, but a worker found the politician’s vehicle abandoned and no sign of the two men.
In a news conference on Wednesday, Mr Denis’s three daughters begged the kidnappers to provide their father with medication to treat his diabetes and hypertension, listing the drugs he takes.
They went to see the location where he was abducted late on Wednesday, they said.
What is the Paraguayan People’s Army?
The EPP is a small Marxist rebel group which has carried out a string of kidnappings and killings in Paraguay.
One of the group’s main sources of income is the smuggling of marijuana and ransoms paid for those it has kidnapped.
