Two murder suspects who escaped from a California jail on Sunday were captured late Tuesday night while trying to cross the southern border back into the United States, according to United States Customs and Border Protection .

The escapees , Santos Samuel Fonseca , 21, and Jonathan Salazar, 20, were arrested trying to re-enter the country near Tijuana, Mexico, Capt. John Thornburg of the Monterey County Sheriff’s Office said at a news conference on Wednesday.

Both inmates, who had been awaiting trial for gang-related killings at the Monterey County Adult Detention Facility in Salinas, Calif., are now facing escape charges, Captain Thornburg said.

The authorities had previously received a tip from someone who claimed to have seen the two men, who are both Salinas natives, at a Motel 6 in California, but when the authorities went to apprehend them, the men were no longer there, Captain Thornburg said.
