A man accused of killing Berta Rios-Lopez in her Denver home nearly 14 years ago has been arrested in Mexico and is awaiting extradition to Colorado, the Denver District Attorney’s Office says. Pedro Rios-Lopez faces a first-degree murder charge in the April 28, 2012, stabbing death of his estranged wife at a home on South Bryant Street in Denver’s Valverde neighborhood. No details about the arrest location or timing were provided. A close friend of Berta Rios-Lopez, who asked not to be identified, said the two women were raising children on their own and hoped to see their daughters grow up together. She described Rios-Lopez as hardworking and focused on building a better future for her children. The friend said Rios-Lopez had told her that her estranged husband threatened to kill her and her daughters. She encouraged Rios-Lopez to seek a restraining order, but said she did not expect the threats to be carried out. The friend recalled celebrating a recent promotion with Rios-Lopez at a Denver nightclub. Afterward, another friend and his partner drove her home, where they reportedly saw her estranged husband outside. The friend said she urged Rios-Lopez not to get out of the car, but Rios-Lopez said she could handle the situation. Rios-Lopez was found stabbed to death in her home the following day, according to her friend’s account. Police launched a nationwide search for the suspect after the killing. The arrest is a significant development for relatives and friends who have waited years for the case to move forward. “Thank God justice will finally be served after 14 years,” her friend said. October is Domestic Violence Awareness Month. Denver officials define domestic violence as an isolated abusive event or a pattern of behavior used to control, punish or intimidate an intimate partner, and say it can take verbal, physical, sexual, psychological, emotional or financial forms.
