A man has been arrested after allegedly shooting three people at a Planned Parenthood clinic.
Robert Lewis Dear allegedly opened fire at the family planning clinic, which provides services for women such as contraception advice, smear tests and abortions.
Three people were killed in the shooting, including 36-year-old mother-of-two Jennifer Markovsky.
Jennifer’s father wrote on Facebook following her death: "To my daughter Jennifer I'm going to miss so much, I lost you in a senseless shooting in Colorado Springs.
"Life was too short my beloved daughter, I was waiting to see you soon.
He finished the tribute with: “I’m going to miss you, my memories of you will love on in my heart and mind! Missing you!!!"
University of Colorado police officer Garrett Swasey, 44, was also killed in the attack. He leaves behind two children and his widow, Rachel Swasey.
Ms Swasey said in a statement over the weekend that "his last act was for the safety and well-being of others".
Iraq war veteran Ke’Arre Stewart, 29, was also killed during the incident in Colorado Springs when he ran into the building to help after alerting authorities.
Gunman Mr Dear will appear in court today.
Our thoughts are with the families and loved ones of those killed in this awful crime.
