UPDATE: The uncle of a Canadian woman who was severely beaten in Mexico over the weekend says his niece is in a medically induced coma and doctors are going to have to perform extensive surgery on her in the coming days.

Robert Prosser of Kingston, N.S., said bones in Sheila Nabb's face were broken from a beating Saturday at her hotel on Mexico's west coast. The 37-year-old Calgary resident was on vacation with her husband.

"They will have to wire her jaw shut and put plates in where her cheek bones should be," Prosser said in a telephone interview.

"It would be three to four weeks before they can move her back to Calgary."

Prosser said he's receiving updates on the condition of his niece, who is originally from the Halifax area, from the woman's mother.

Nabb was on vacation at the Hotel Riu Emerald Bay in Mazatlan with her husband, Andrew Nabb, who is still in Mexico with her, Prosser said.

He said he was told Nabb was found in a pool of blood in a hotel elevator by staff. He said police are investigating.

"Pray for her recovery and think twice before you go to Mexico," said Prosser.

"Every bone in her face is broken. ... They have to wire her jaw shut because it's all broken and they have to put some plates where her cheeks were because the bones are all shattered," he told the Chronicle Herald in a separate interview. He also said that Nabb may have to stay in Mexico for weeks before she can be moved.

Prosser told CBC that the family does not know what motivated the attack.

"We have no idea yet who's done this," he told the CBC in an interview.

Prosser also told the network that Sheila's husband Andrew Nabb is with her at a hospital in Mexico. "He's taking it quite hard but he's getting through it," Prosser said.

"Right now our biggest concern is getting her well enough to get her home," Prosser added.

Images of Andrew and Sheila Nabb's wedding at the Mandalay Bay Resort and Casino in Las Vegas were posted to a public Facebook page Andrew created.

Prosser told QMI Agency that Andrew woke up at 6 a.m. in the Mexican hotel and found his wife was not in the room. By then, Sheila had been taken to hospital, he said.
