The dragnet for escaped inmate and suspected murderer John McCluskey along with his girlfriend is now in its third week, and they seem to have simply disappeared.
The last credible sighting of McCluskey and Casslyn Welch, who authorities call a modern day Bonnie and Clyde, was on Aug. 6 in Billings, Mont.
Authorities are combing the rugged terrain along the U.S.-Canadian border of northwestern Montana, although according to the marshals the duo may already be deep inside Canada. A reward of $35,000 is being offered for any informaiton leading to the arrests of McCluskey and Welch.
Officials believe they may have dyed their hair or taken other measures to change their appearance since Welch allegedly helped McCluskey break out of an Arizona prison on July 31 along with two other convicts. The two accomplices have been recaptured, but McCluskey and Welch have eluded a massive dragnet.
The couple is believed to still be traveling together and still driving a car they were given in Phoenix, possibly by an accomplice.
"It is believed they are still driving the 1997 Nissan Sentra sedan (gold, gray, or tan in color). The Sentra originally bore Arizona license plate 620 PFV, however, the plate may have been switched," Richard Tracy of the Arizona U.S. Marshals said in a statement Monday.
Sightings have placed the duo from Amarillo, Texas, to Yellowstone National Park in Wyoming, according to U.S. Marshals. Police also believe a 60-year-old couple whose charred remains were found in a burned camper in New Mexico were killed by McCluskey and Welch before they took their pickup truck.
They are considered to armed and extremely dangerous.
While McCluskey and Welch have the headlines, there others that the marshals and the FBI are hunting. Here are seven of the country's most wanted fugitives:
Eduardo Ravelo, one of the FBI's Top 10 Most Wanted Fugitives, is an alleged captain and hitman for the Barrio Azteca criminal enterprise. He is accused of racketeering, money laundering, drug trafficking and numerous murders since 2003.
Ravelo is believed to be in his 40s, according to the FBI, and goes by numerous nicknames, including "Tablas." He has a scar on his face and has ties in Mexico and El Paso, Texas, according to the FBI.
A reward of $100,000 is being offered for information leading to Ravelo's arrest, and he is considered armed and extremely dangerous. Anyone with any information is asked to contact their local FBI field office.
