A 1-year-old whose father took off with him after allegedly stabbing another man was found safe late Monday in Tijuana .

The father, Giovanny Santiago-Enriquez, 37, is in custody, according to the Los Angeles Police Department. The U.S. Marshals made the arrest in Tijuana, officers said.

The U.S. Marshals said its counterpart agency in Mexico, La Policía Estatal Preventiva, made the identification based on the alerts that went out, surveilling the vehicle matching the description as it was parked on a street. The suspect and child were then seen walking toward the car when the arrest was made without incident about 8:15 p.m.

Santiago-Enriquez is being detained in Mexico, said Bert Tapia, acting chief inspector for the U.S. Marshals.

He was wanted in connection with the stabbing of the boyfriend of his son’s mother.

“I still don’t have him, apparently he’s in Mexico,” the relieved mother, Christy Martinez, said in a short telephone interview about 30 minutes after she received word that her son was found Monday night. “I’m going to drive over there with (the police).”

Santiago-Enriquez, who had been watching Jayden Santiago at his Long Beach home, allegedly went to the home of Martinez, his ex-girlfriend, near 15th Street and Grand Avenue in San Pedro about 1:30 a.m .

She said the family was awakened when he came into the house and then into the bedroom.

“He just looked at me, he had a knife, and stabbed my boyfriend six times (in the body) and three times in the head,” said Martinez, 20.

The child, she said, apparently was left in the car parked a block away during the assault.

Martinez said her two-year relationship with Santiago-Enriquez was marked by domestic violence and that they finally separated about two months ago.

About a week ago, she said her current boyfriend was arrested after an altercation that began when Santiago-Enriquez came by the couple’s home and hit the boyfriend in the back of his head, sparking a fist fight that landed them both in the same emergency room. Only her boyfriend was charged, she said.

Distraught over her missing child, Martinez said Monday that she didn’t think Santiago-Enriquez would hurt the boy.

“He loves him too much,” she said. “But then again, he did all that (the stabbing) while the baby was in the car. … He’s just a man with a lot of problems, anger problems, and he’s suicidal,” she said, fighting back tears. “I haven’t slept all night. I’ve looked everywhere that I think he could be.”

Santiago-Enriquez has attempted suicide in the past, officials said.

Authorities noted that he has legal custody of the boy.

The woman’s boyfriend was being treated at an area hospital.
