CANCUN, Mexico — Mexican officials say a candidate for city council in the Caribbean resort of Isla Mujeres has died after being shot at a political event.

Quintana Roo state prosecutors said Tuesday that Rosely Magana died from her injuries the previous night. Magana was shot along with another party activist Saturday in the mainland portion of Isla Mujeres north of Cancun.

Magana was a candidate for the ruling Institutional Revolutionary Party in the July 1 elections.

Quintana Roo Gov. Carlos Joaquin condemned the killing. Mayoral candidate Juan Carrillo Soberanis and a member of Magana’s party suggested the killing was politically motivated.

The risk-analysis firm Etellekt says Magana was the 15th candidate killed in Mexico during this election cycle.
