The mother of the Uvalde school shooter was confronted in the street by family members of one of his 21 deceased victims.
Adriana Martinez had been walking across the street in the small Texas town when relatives of one of the 19 children her son killed at Robb Elementary School on May 24 approached her, Telemundo reported.
"You have no right to judge my son!" Martinez shouted over at relatives of the late 10-year-old fourth-grader Amerie Jo Garza. "May God forgive y'all."
The verbal altercation kicked off when a black SUV with some of Garza's relatives inside stopped in the middle of the street to confront Martinez who was seen crossing the road, footage by Telemundo shows.
Some of those inside the vehicle rolled their windows down as others exited the car to shout at Martinez - the mother of 18-year-old Salvador Ramos who shot dead 19 children and two teachers at a local elementary school.
"What reason did he have? Because he was pissed off at you? Because you destroyed him?" one relative shouted.
"What reason did he have to kill 21 [people]," another family member screamed.
Martinez responded: "I didn't know."
She went on to add: "I know my son was a coward. You don't think I don't know that? I know. You don't think I'm carrying all that with me? You don't think I don't know. I know. And I'm sorry."
Garza's family had just left a meeting with other loved ones of the 19 young victims when the confrontation took place, Telemundo reported. It was not noted by the outlet whether Martinez was at the same meeting.
Just days after the May 24 rampage, Martinez told CNN her son "had his reasons for doing what he did and please don't judge him."
Martinez asked for forgiveness for herself and her teen son, who was ultimately killed by officers who attended the scene.
"I only want the innocent children who died to forgive me. Forgive me, forgive my son. I know he had his reasons," she said.
The massacre in the town of Uvalde was the deadliest shooting at a school in the US since 20 children and six adults were shot dead at Sandy Hook Elementary in Newtown, Connecticut, in December 2012.
The young gunman entered Robb Elementary School at around 11:32 AM. He was armed with a handgun and an AR-15 semi-automatic rifle before "horrifically, incomprehensibly" opening fire, Texas Governor Greg Abbott said.
“My heart is broken today,” said Hal Harrell, the school district superintendent, per The Guardian. “We’re a small community, and we’re going to need your prayers to get through this.”
