Mexican prosecutors have launched an investigation of possible criminal conduct in the case of a 14-year-old girl mistakenly sent to the U.S. to live with a woman who claimed to be her mother, authorities said Friday. Alondra Luna Nunez was mistakenly flown to Texas on April 16 after a judge in the western state of Michoacan ruled in favor of a Houston woman who believed she was her daughter. She was returned to her family in Mexico on Wednesday after DNA testing in the United States showed she was not the long-missing daughter of Houston resident Dorotea Garcia. Scroll down for video . Reunited: Alondra Luna Nunez (pictured) was mistakenly flown to Texas on April 16 after a judge in the western state of Michoacan ruled in favor of a Houston woman named Dorotea Garcia who believed she was her daughter . The Prosecutor's Office in the southwestern state of Michoacan said in a statement that it is looking into the case involving a civil court judge in Los Reyes, including media reports and videos that 'suggest probable acts against the child's best interests and could constitute an illegal action'. Video footage of Alondra being taken screaming by police circulated widely and attracted national and international attention to the case. The National Human Rights Commission has launched its own investigation, which its president Luis Raul Gonzalez said would seek to ensure that there is 'no impunity' in the case. After landing home on Wednesday, Alondra seemed to hold no grudge, saying she hoped Garcia, ended up finding her daughter. They spoke by phone. Taken: Alondra Luna Nunez's case drew international attention after a video of her being forced into a police vehicle last week appeared online . Struggle: Alondra used every ounce of her energy to fight Mexican federal police officers, who were working for Interpol on the orders of a Texas judge . 'She told me to forgive her for everything she had done to us,' Alondra told reporters. Alondra had asked for DNA tests in Mexico before she was sent to the United States, and her parents presented more than a dozen documents including her baptismal records, family photographs and a copy of her birth certificate. But Judge Cinthia Elodia Mercado ruled Alondra was in fact Alondra Diaz Garcia, who was taken from Texas by her father in 2007. Garcia thought Luna was her daughter because they share a similar scar between their eyebrows. The other girl remains missing and the father's whereabouts are also unknown. Elodia Mercado said this week that it was not within her authority to order DNA testing, and she was obligated to ensure Mexico followed international conventions on child abductions. 'We, as judges, are only responsible to resolve the case with respect to recovering the minor,' she said. 'We don't do investigations or make inquiries.' Mexico's National Human Rights Commission also announced it had requested reports from a half dozen government entities to conduct its own inquiry into whether Alondra's human rights were violated. Reunited: Alondra is seen with her father, little brother and mother after she was reunited with her family when a DNA test proved she was not the daughter of the Houston woman . Long-lost daughter: Dorotea Garcia (pictured) believed that Alondra Nunez was her long-lost daughter Alondra, who was taken to Mexico by her father in 2007 . Similarities? Dorotea never stopped looking for her daughter Alondra Diaz Garcia - seen here before she was taken as (right) in a digitally aged picture . It added that its officers had interviewed Alondra's father and offered medical and psychological help for the girl and the family, and said it would study whether procedures for handling such cases should be reformed. 'If there are holes or gaps in the protocol, these must be corrected to prevent future human rights violations that harm girls, boys and adolescents,' the commission said in a statement. After the ruling, Alondra traveled by bus with Garcia to the U.S. border, crossing at Laredo, Texas. Alondra was granted entry based on the birth certificate of Garcia's daughter and the court order, according to Mexico's Foreign Ministry. This week, when asked if she harbored any anger about the forced weeklong separation from her family, Alondra, singled out the judge. 'I'm angry only at her, because it was her who caused all this,' Alondra told The Associated Press. 'Nobody but her is guilty. At least that's what I think.'
