-LRB- CNN -RRB- -- A man authorities believe has robbed at least 10 banks in at least four states was arrested in Missouri after a retired state trooper saw him and learned he was wanted , authorities said Sunday . Schaffner is seen in a police mug shot after his arrest Saturday in Kingdom City , Missouri . Chad Schaffner , 37 , was arrested in Kingdom City , Missouri , about 2:45 p.m. Saturday , said Missouri State Highway Patrol radio operator Paula Price . Sam Lakey , a retired Missouri State Highway Patrol officer said he alerted authorities to Schaffner 's whereabouts after seeing him at a motel in Kingdom City , about 100 miles west of St. Louis , Missouri . Lakey did n't know who Schaffner was at first , but said he felt something was n't right after seeing Schaffner and his car , partly because Schaffner did n't make eye contact with him . Watch how ex-cop 's hunch brought arrest '' Lakey , who was staying at the motel , said he remembered seeing news reports about a man sought in a string of bank robberies , so he looked on the Web site of the television show `` America 's Most Wanted '' to check a vehicle description in the case . A license plate number on the site matched that of the car outside the motel , he said . `` I felt my goosebumps raising , '' he said . Lakey told CNN that after calling his old colleagues at the Missouri State Highway Patrol , he packed up his family from their room at the motel and watched the arrest from across the street . Schaffner faces charges including bank robbery in Tennessee ; burglary in Indiana ; armed robbery in Illinois ; and receiving stolen property in Ohio , Price said . He also faces drug charges in Missouri , she said . Schaffner is suspected of robbing banks in states including Kentucky , North Carolina , South Carolina and Tennessee , according to the FBI . Schaffner is suspected in 14 robberies of various types in six states , FBI Special Agent Brian Truchon told CNN on Sunday . A spokeswoman for the Callaway County Jail , in Fulton , Missouri , said Schaffner was booked into the facility about 8 p.m. Saturday . No bond has been set , she said . Schaffner will appear in court Monday in Jefferson City , Missouri , according to Bridget Patton , spokeswoman for the FBI 's Kansas City , Missouri , office . Schaffner was identified as a suspect last month after investigators posted surveillance photos from the robberies on electronic billboards throughout the South . In the photos , a man was seen sneering and holding a pistol sideways . The robberies began in May . While no one was harmed , the FBI said they considered the suspect dangerous . `` This guy has made no effort to hide the gun , '' said FBI agent Kevin Keithley last month . `` He has threatened the use of it in every bank robbery he has committed . He has put the gun in the faces of the tellers , threatened to use the gun against them . So we want to get this guy in custody before he harms anyone . '' A woman in Morristown , Tennessee , also told authorities Schaffner hid in her apartment in August and threatened to kill her children if she revealed his whereabouts , according to documents filed in federal court . When Schaffner was identified , the FBI said he was released from an Indiana prison last year following an armed robbery conviction . He also has several other convictions in Indiana , for crimes including burglary , resisting law enforcement , and purchase of a handgun without a license , according to the Indiana Department of Correction . The last bank robbery Schaffner is suspected of committing occurred in Caseyville , Illinois , on Wednesday , according to CNN affiliate KMOV . Two bank robberies occurred in Morristown and Jefferson City , Tennessee , on August 18 , authorities said . The billboards began showing images from the robberies on August 24 , and the next day , a man told the FBI that Schaffner was in the Morristown area at the time of the August 18 holdups . The man said he 'd known Schaffner for about two months , according to a federal criminal complaint . FBI agents also interviewed a Morristown woman after hearing she 'd had a brief relationship with Schaffner , the complaint says . During the first interview , she spoke to agents outside her apartment and denied knowing him , the complaint said . But the next day she told authorities she knew Schaffner and that he had been in her apartment with her children while she talked to police outside . He had threatened to kill the children if she told agents he was there , the woman said . CNN 's Marylynn Ryan , Chuck Johnston and Justin Lear contributed to this report .
