Police issued an Amber Alert Tuesday for a 12-year-old girl who they say was abducted by a 25-year-old co-worker of her brothers.

Margarita Aguilar-Lopez (search) was last seen Monday night at a Bradenton motel, where she was staying with two brothers who had left her in the care of Antonio Paulino-Perez (search).

When the two brothers returned to their room at the Classic Inn at about 8 p.m. Monday, the child and Paulino-Perez were missing, police said. Police said Paulino-Perez is suspected of taking the girl.

The brothers did not report the girl missing until Tuesday morning, even though a Bradenton police officer had spoken to them at the motel at about 10 p.m. Monday while investigating a battery complaint against one of them, Rubino Aguilar.

When asked about the delay, one brother told police that he and his brother were "too intoxicated and could not remember." Police did not immediately release where the siblings' parents were or the brothers' ages or occupation.

Margarita is a Mexican citizen, 4-foot-10 and 65 pounds with black hair and brown eyes. She was wearing a white T-shirt and blue pants.

Margarita's parents are in Mexico. She is an illegal immigrant living with her two brothers and her sister-in-law at the motel. Margarita babysits her brother's children while the family's adults work at migrant labor in Ruskin, said Major William Tokajer, Bradenton police spokesman.

Paulino-Perez is 5-foot-2 and 120 pounds with black hair and brown eyes. He may be driving a red van, police said.

Bradenton, on Florida's Gulf Coast, is about 20 miles south of Ruskin, where 12-year-old Sarah Lunde (search) was found strangled in a fish pond earlier this month, and about 110 miles south of Homosassa, where 9-year-old Jessica Lunsford (search) was sexually assaulted and slain in February. A former boyfriend of Sarah's mother is charged with her death and a part-time neighbor is accused of killing Jessica.

Anyone with information about the case is asked to call the Bradenton Police Department at (941) 932-9300.
