An official in Mexico has confirmed that a 74-year-old Canadian photographer was killed in the Yucatan state.
State prosecutor spokesman Baruch Velasquez identified the Canadian as Barbara McClatchie Andrews.
Velasquez says she was a resident of Merida, the capital of Yucatan.
He says McClatchie Andrews ran an art gallery in the centre of Merida called "In Lak'Ech''.
According to the gallery's website, McClatchie Andrews spent part of her early career as a photojournalist, publishing in National Geographic.
But in later years, she turned her focus to abstract photography.
In a news release, the state prosecutor says the woman was found dead Friday morning on the side of the highway connecting Merida with Cancun.
The statement says the victim was strangled to death.
