SAN DIEGO -- Family and friends were shocked to learn of Jarritt Monzingo's imprisonment on murder charges in Tijuana.

Monzingo, 22, and 27-year-old Joshua Dockery are U.S. sailors and both are in a Tijuana jail facing charges of murder.

Earlier this week, Dockery's father -- who lives across the river from Philadelphia in New Jersey -- spoke on his son's ordeal.

Monzingo hails from a small town called Cabool, located in Missouri.

Monzingo, who weighed all of 110 pounds his senior year at Cabool High School, wanted one thing above all else -- to be a Navy SEAL.

He began BUD/S school, or Basic Underwater Demolition, to become a Navy SEAL.

Now, he is in Tijuana facing charges of attempting to kill a woman known as Belen.

"When I heard the noise coming from my sister's room the man started stabbing me in the chest with a knife," said Belen.

Belen and her sister, both prostitutes, were savagely attacked in a Tijuana hotel room.

"I cannot imagine him doing this. The only way I could ever fathom him doing that was if he was afraid for his life," said family friend Cathy Wells.

It's a sentiment Monzingo's former high school coach Joel Easter echoes as well.

"Not everybody gets to be a Navy SEAL, and if that is indeed what he wants to do I can't see him make that big a mistake throwing that away unless his life was in danger," said Easter.

Worse still, according to Mexico's state Attorney General Salvador Ortiz, is that the two men are also accused in the murder of another prostitute a month earlier.

Once news of the February attack become public, witnesses identified the Dockery and Monzingo as the two men who were at the Lafayette Hotel where Mayte Victoria Delgado Flores' body was found on January 17.

Tijuana Mayor Jorge Ramos said, "He who breaks the law in this country will pay the consequences … in this case we are trying to be hospitable with the tourists but they will pay for their crime."

Investigators said other women at the hotel where Flores was killed were also attacked and identified both sailors.

The U.S. Navy is in contact with the sailors and is looking out for their personal welfare.

The two men are currently at the La Mesa prison in Mexico.
