cmannphoto/iStock(CIUDAD JUAREZ, Mexico) — Sorrow and outrage overwhelmed mourners gathered in Ciudad Juarez, Mexico, to welcome home and bid farewell to a beloved school principal who was one of the 22 people killed while shopping at a Walmart in El Paso, Texas.The funeral Wednesday for 57-year-old Elsa Mendoza de la Mora was the first for the victims slain in mass shootings in El Paso and Dayton, Ohio, that occurred on consecutive days over the weekend and sent shock waves across the United States and Mexico, prompting new calls for action to stop gun violence.“Personally, I am very outraged because this is unfair for her and for the other people that died. They did not deserve this,” Alma Vargas Marquez told Telemundo TV network outside the funeral home where her cousin Mendoza de la Mora’s funeral occurred.Mendoza de la Mora’s body arrived in Ciudad Juarez in a black Cadillac hearse that was escorted by motorcycle police on the 7-mile journey across the southern border from El Paso.Marquez and other mourners were already gathered outside the funeral home when the hearse pulled up and pallbearers dressed in black suits carried a gray casket bearing the body of Mendoza de la Mora inside.Another cousin of the slain woman, Ruth Vargas Marquez, said she wishes the deaths of the 31 people killed in both massacres will finally be a “call to consciousness.”“This is the moment that we leave behind hatred, racism, fear and do things differently and unite,” Ruth Vargas Marquez told Telemundo. “I think the message of Elsa is to keep loving each other and make things different.”Mendoza de la Mora was a mother of two children and a special education teacher and principal of the Rafael Veloz Elementary School in Ciudad Juarez, relatives said. Her husband, Antonio de la Mora, described her as “the most wonderful of women” in a Facebook post.She was inside the Walmart shopping when alleged gunman Patrick Crusius, 21, walked through the front door about 10:30 a.m. Saturday firing an AK-47-style rifle, investigators said. Her husband and son were waiting for her in a car in the parking lot when the gunfire erupted, authorities and relatives told reporters.In addition to the 22 people killed, more than two dozen were injured.The volunteer group Operation H.O.P.E. (Helping Other People Endure), which provides clothing, shoes and even food for the needy in the city, has volunteered to cover the funeral expenses of all the victims in the Walmart shooting.Following his arrest, Crusius told investigators he was bent on killing as many Mexicans as possible and authorities suspect he is the author of an anti-immigrant screed posted on the controversial online message board 8chan just before the attack.The mass shooting came a day before nine people were killed when a gunman went on a killing rampage in Dayton, Ohio.Memorial services for the victims in both shootings area scheduled to continue through the weekend and into next week.Earlier this week, the youngest victim killed in the El Paso shooting,15-year-old Javier Rodriguez, was mourned by his teachers and classmates at Horizon High School in El Paso.“Javier was just a young man full of life, running in this same stadium we’re in now,” Juan Martinez, superintendent of the Clint Independent School District, said at the vigil for the Javier held on the football field at the school. “He didn’t deserve to die in a tragedy like this.” Copyright © 2019, ABC Radio.
