The teen was walking out of ROTC after school when she saw the lights flashing and heard the horn blaring from her mother's black SUV.

The girl's stepfather was beside the driver's side window, confronting his estranged wife.

The teen dropped her backpack and ran to help her mother, but abruptly stopped.

"Grace! Run! Run!" Gladys Tordil yelled to her daughter.

Those were the last words the mother uttered before the man at the SUV — Gladys Tordil's estranged husband — shot his wife and walked away.

More than a year later, a judge on Wednesday sentenced Eulalio Tordil, 65, to two life terms for the killing of Gladys Tordil and the attempted murder of a good Samaritan who tried to intervene in the school lot.

The sentence in Prince George's County Circuit Court closes a case that set the Washington suburbs on edge as Tordil went on a two-day shooting rampage that left three dead and three others wounded.

"You should not see or breathe a free bit of air for the rest of your life," Prince George's County Judge Leo Green Jr. said before sentencing Tordil. "It's overwhelming the reasons to show no mercy."

Green ordered the two life sentences to run back-to-back on top of the four consecutive life sentences Tordil previously received in Montgomery, where Tordil shot two strangers during his attempts to steal cars and elude police.

Surveillance video from the high school played during Wednesday's sentencing hearing showed Tordil shot his wife through the window of the SUV. He ran toward his car to flee but quickly turned back. He then stretched his arm through the window of the SUV once more, appearing to shoot his wife again before leaving. "My stepfather came out of nowhere!" Grace Glimada screamed to an operator during a 911 call played in court.

When given the opportunity to speak on Wednesday, Tordil spent a few minutes telling the judge about his career in law enforcement and talking about how he "never got in trouble" in his life.

"I'd like to apologize to my family," Tordil then said.

Tordil had gone to the parking lot of High Point High School on May 5, 2016, two months after his wife filed a protective order against him. He rented a car that morning and packed a bag with a toothbrush, clothes and $1,800 in cash. He also had a cache of ammunition and a single gun he kept hidden from law enforcement, despite court orders to turn in all of his weapons.

The former Federal Protective Service officer, who had just lost his job, went to the parking lot with a plan to kill, prosecutors said. In a journal, which prosecutors detailed in court during his sentencing in Montgomery, Tordil wrote that his marriage had "reached a point of no return." He asked "God and the potential victims . . . for forgiveness."

During a massive manhunt the day after killing his wife, Tordil shot Malcom "Mike" Winffel, who was coming to the aid of a woman whose car Tordil was trying to steal at a mall in Montgomery County, and Claudina Molina, who was fatally shot by Tordil as he tried to take her SUV outside a grocery store.

Tordil's attorney, David Booth, said his client grew up in a strict Catholic upbringing and chose a career in a regimented military system. When his wife and daughters left him and he lost his job, "he broke," Booth said. Tordil became depressed and sat at home alone in the dark, Booth said.

"His life was just beginning to crumble and tumble out of control," Booth said. "These two days aren't really who he is."

Booth argued that Tordil should have the opportunity for parole, which the judge denied.

Prince George's Assistant State's Attorney Rebecca Cordero said that Tordil didn't deserve any mercy. "He shattered the lives of so many people," Cordero said.

Not only did he kill and wound several people, but he stole the sense of safety people had in a "sacred" place like a school by confronting his wife in the parking lot packed with students and parents.

A man who had arrived at the high school to watch his son's baseball game was shot in the arm when he ran to help Gladys Tordil, Cordero said. The man remains haunted by violence, and his son has not played baseball since that "horrific" day, Cordero said.

Gladys Tordil's children spoke in court, sobbing as they talked about how much they miss their mother. They were seniors who were one week away from graduating when their mother was killed.

At a time when they should have been excited about prom and preparing for college, Nikki and Grace Glimada were instead attending a funeral and memorials.

The girls also admonished Tordil, who they said was abusive and created a "house that was toxic."

Nikki Glimada recalled her mother as strong, smart and independent, saying she lost "a role model, a friend, a mom."

"She was everything I wanted to be," Nikki Glimada said.

Grace Glimada called her mother's killing "the worst day of my life," listing the college graduations, grandchildren and other life milestones Gladys Tordil would never see.

"She's only seen one-third of our lives," Grace Glimada said.
