WASHINGTON (CNN) -- The FBI has put Rafael Resendez-Ramirez, the man suspected of being the so-called "Railway Killer," on its 10 Most Wanted list.

The announcement was made Monday afternoon.

In addition, Illinois authorities on Monday charged Resendez-Ramirez in the slayings of an 80-year-old man and his 51-year-old daughter whose bodies were discovered last week in Cairo, Illinois.

The FBI is also investigating whether Resendez-Ramirez is connected to two more killings in Rockford, Illinois.

The FBI says the suspect is implicated in six other killings in Texas and Kentucky. In addition, he is suspected in as many as 14 other murders ranging from Miami to Detroit and Phoenix, CNN has learned.

In at least six killings -- one in Lexington, Kentucky, the other five in the Houston and San Antonio areas of Texas -- all the victims were beaten or stabbed to death. Their bodies were found near railroad tracks.

FBI officials fear the killing spree may be intensifying.

Two of the six killings Resendez-Ramirez has already been implicated in came on June 4 and June 5. The four killings in Illinois quickly followed.
