A Mexican activist and mother of an autistic child has died after being set on fire, authorities said

Luz Raquel Padilla, 35, was doused in alcohol by three men and a woman and set alight in a park in Zapopan in Jalisco state, prosecutor Luis Joaquin Mendez said, citing witnesses.

Padilla, part of the caregivers’ rights group “I take care of Mexico,” died in a hospital on Tuesday after suffering burns on 90 percent of her body, according to authorities.

The case is being investigated as a possible femicide, prosecutors said.

One of Padilla’s neighbors, Sergio Ismael “N,” was arrested for causing injuries, making threats and crimes against a person’s dignity in connection with previous incidents, Mendez said.
