Investigators and the mother of a 3-year-old boy snatched from his San Bernardino home on Sunday fear Briant Rodriguez may have been taken to Mexico.

The FBI and San Bernardino County sheriff’s detectives said there is no information yet on why this family was targeted, but the California Highway Patrol has issued an Amber Alert.

Rosa Millana, who was tied up inside the house with four of her children when Briant was taken, said she just wants her youngest son back.

She dissolved into tears several times Monday afternoon while speaking about the ordeal, which unfolded in her Pedley Street home about 2:30 p.m. Sunday.

“They said they were going to take the baby to Mexico and they were going to kill him,” said family friend Nancy Vargas, who translated for Millana.

Two armed men walked into the family’s small, white, one-story home through the front door, which had been left open because Millana was about to take the kids to the park.

They tied the family up with tape while they ransacked the home for about 20 minutes, officials said. Although the men took Millana’s cell phone and cash from her jacket pocket, they did not take a flat-screen television.

The men then left, taking Briant with them. Millana heard a car door slam but there were no witnesses outside to describe the vehicle.

Briant’s 8-year-old brother managed to wiggle free within minutes and untied the family. Millana immediately ran about two blocks to Shop-Rite Market & Liquor and borrowed the shop owner’s cell phone to call 9-1-1. The boy’s father was at work when his son was taken.

“My mom’s very tired thinking of my little brother, where he’s at,” said 16-year-old Jose Barraza, who left for a friend’s birthday party shortly before the intruders broke in. “I ask whoever has him to come back.”

Sheriff’s spokeswoman Jodi Miller said the kidnappers have not contacted the family for ransom and “we are concerned the child has been taken across the border.”

Border Patrol has been notified of the abduction. Even though an Amber Alert was sent out about 1 a.m. Monday, electronic freeway signs are not displaying information because there is no vehicle description.

A sheriff’s deputy spent the day parked next to the family’s home. Children briefly came out of the house, riding bicycles in the front yard, but mostly stayed inside.

Briant’s father, Raul Rodriguez, sat on a stoop in the back yard with his head dropped to his chest. His eyes were red-rimmed when he declined to comment.

The boy is 3-feet tall, weighs 40 pounds and has brown eyes and brown curly hair. Briant was last seen wearing a yellow shirt with blue sleeves, blue striped shorts and black sandals.

Family members said the boy loves SpongeBob Squarepants.

The suspects are both said to be skinny, Spanish-speaking Latino men. One is said to be 18 years old, 5-foot-8 and wearing a black ball cap, blue jeans and a green T-shirt. The second suspect was about 24 years old, 5-foot-10 and was wearing a black shirt, black pants, black boots and a white bandana.

Anyone with information is asked to call the Amber Alert hot line at (866) 346-7632 or sheriff’s Sgt. Doug Hubbard and Det. Jon Minard at (909) 387-3589.

This reminds me of the Cole Puffinburger case. Cole was kidnapped as the result of drug money disappearing. The boy was later released safely. Or maybe the men kidnapped Briant because someone wanted him. With those long curls he is a very striking child.
