The bodies of the 25 people killed in a bus accident in the western Mexican state of Nayarit are being returned to the northern state of Chihuahua, where they were from, officials said.

A bus carrying tourists from Chihuahua plunged into a ravine around 4:00 a.m. Friday in Nayarit.

The accident occurred on a stretch of highway between the towns of Puente de Chapalilla and Tequepexpan, state officials said.

Officials in Nayarit reported the death toll as 24, but the Chihuahua government said 25 bodies were being returned to the northern state.

The vehicle transporting the bodies is expected to arrive at the coroner's office in Chihuahua city, the state capital, on Sunday morning.

"From the moment that the Chihuahua government learned of the accident and on the orders of Gov. Cesar Duarte, personnel from the government's General Secretariat were sent to the accident scene to care for the injured, receive and transfer the bodies, as well as to carry out the corresponding legal procedures," the Chihuahua state government said in a statement.

"In addition, the General Secretariat of the Chihuahua Government sent a team of doctors, who evaluated each of the injured people to determine who could possibly be transferred and continue their recovery at hospitals in the Chihuahuan capital," the state government said.

About 20 people are hospitalized at different medical facilities in Nayarit, Chihuahua government spokesman Juan Ramon Flores told reporters.

Gov. Duarte has spoken with Nayarit Gov. Roberto Sandoval about the injured to make sure they receive the best treatment possible, Flores said.

Relatives of the injured will only be sent to Nayarit if the situation warrants it, the Chihuahua state government spokesman said.

"If we find in the next two or three days that some of the injured will have to stay there, we are going to do an extensive evaluation so one of their relatives can go to Tepic (the capital of Nayarit) and can accompany their loved one," Flores said on Saturday.

Ten people have been treated and released from hospitals, Chihuahua General Secretariat official Oscar Garcia said.

The group from Chihuahua was heading to Rincon de Guayabitos, a seaside resort about 60 kilometers (37 miles) north of Puerto Vallarta.

Schools let out in Mexico earlier this month and highways are crowded with families en route to vacation spots. EFE
