(CNN) -- A tip from a television viewer led to the arrest of a Florida man accused of killing four of his family members on Thanksgiving Day, authorities said early Sunday. 

Paul M. Merhige is accused of fatally shooting his twin sisters, a 6-year-old cousin and a 79-year-old aunt at a family home in Jupiter, Florida, on November 26. One of his sisters was pregnant. 

Authorities say Merhige also wounded two other family members. 

A viewer of "America's Most Wanted" recognized descriptions of Merhige and his car, authorities said at a news conference early Sunday. Officers immediately responded to the tip late Saturday, surrounding a small motel in the Middle Keys, part of the Florida Keys. 

Merhige, who had apparently been at the Monroe County motel since December 2, did not resist apprehension by U.S. marshals, authorities said. It was not immediately clear whether he was armed when marshals burst into his motel room, more than 200 miles from Jupiter. 

Merhige made a first appearance in a West Palm Beach, Florida, court later Sunday morning in a hearing that lasted only minutes, according to CNN affiliate WPTV. He is charged with four counts of premeditated murder and attempted first-degree murder. 

Asked by the judge if he had anything to say, Merhige declined comment, WPTV said. His next court appearance is scheduled for February 1. He will be held without bond at the Palm Beach County jail. 

Jim Sitton, father of 6-year-old Makayla, who was killed, told CNN affiliate WPTV late Saturday that he would "sleep a little better tonight."
