Smyrna officials called off the search Tuesday for 28-month-old Analyce Guerra and said they are focusing on interviewing the toddler's friends and family to determine her whereabouts.

An Amber Alert was issued for the Tennessee girl after her mother woke up Monday morning to find the front door of the house open and her daughter missing.

Analyce was last seen in the Meadowwood Apartments off Nissan Boulevard in Smyrna, according to FOX affiliate WZTV in Nashville. Eva Guerra told police she last saw her daughter asleep in the family's apartment Sunday evening. When she got up before dawn for a drink of water yesterday, Guerra said Analyce was gone and she found the front door unlocked.

Search crews were looking for the girl all day Monday and continued their search Tuesday. Authorities and volunteers have searched nearby Stewart Creek.

A candlelight vigil was held Monday night for Analyce and her family set up a display outside her home in hopes she will return safely.

"We haven't had any kind of contact with the baby any time within the last 24 to 48 hours," Smyrna Police Sgt. Ken Hampton told FOX News on Tuesday. "We're still looking to speak with a couple of family members we haven't been able to locate."

Police have been questioning family members and friends of the Guerras.

"Right now, the family is what we're focusing on and friends, anybody, like I said, that was close to this child. It's just very suspicious for a 1 1/2-year-old child to be able to get up, unlock the door and walk out" without a trace, Hampton continued.

"We're trying to make sure we cover all our bases here."

He said the two miles surrounding the apartment complex had been repeatedly searched by Tuesday afternoon and police were convinced Analyce was not there. "We felt comfortable enough, we didn't get any evidence or anything to believe she was still in that area."

The girl's father, who lives in Nashville, is not under suspicion at this time, Hampton said, and has been active in the search.

Smyrna Detective Scott Byers says finding the girl is the priority, regardless of whether a suspect is named in her disappearance.

Byers said the investigation is hindered by language. Many people who live in the apartments where the child disappeared are Hispanic. The police department has only about a half-dozen officers to who Spanish.

Anyone with information is urged to call TBI-FIND.
