Tucker Monroe, before Hartman and Thorne killed him in return as Donahue was about to shoot Oliver Greico. Hartman and the team tracked down an another suspect Vance Ferguson, Donahue 's biological father, who had orchestrated the conspiracy in order to make high profit on a real estate venture.
Hartman and the squad struggled with the aftermath of the shooting throughout the season as the public blamed the department for it, and the detectives searched for the one responsible for re-enabling the gun used in the shooting. This was exacerbated with the appearance of IA Sgt. Oakland Everett, who was assigned to keep on eyes on the team. Hartman dealt with the news of Jack and Lauren becoming parents and Linda Young's depression. Later, undercover cop Ariel Vargas began interfering during their investigation of two officers raping a female colleague. The squad detested her meddling in the case until Hartman discovered Vargas was not only District Attorney Fontana's daughter, but also a witness to the rape and got video proof of the rapist officers before and after the rape. After the officers were convicted and sentenced, Hartman helped Vargas join the squad for short time while Young was on medical leave. Vargas remained in contact with Hartman and the team after Young returned.

At the hospital, Lauren gave birth to Hartman's grandson, Jason Maximilian Hartman. But Jack and Eddie were accused by Internal Affairs of killing the hostage with friendly fire. But new M.E. Lucien Novač told Hartman that he discovered in autopsy that the hostage was actually killed by someone else's bullets. She eventually learned that the hostage's husband was cheating on her with her marriage counselor and he used the robbery as a ploy to assassinate her in disguise for her fortune. With Jack and Hicks cleared, they celebrated Jason's birth at last.
After she was promoted to Captain after Thorne's retirement, Hartman assumed control of the MCS. She had to deal with some serious cases and the brash new detective Jonas Boscorelli. When Angela Fontana and her boyfriend, who despises cops after they arrested his racist father, vandalized Hartman's office and send pictures of it online, the irate Hartman angrily confronted Angela for her role and put her in custody. After learning Angela's bipolar disorder and drug use, she discovered Angela's anger started because of the aftermath her father Gordon's actions, blaming her father for his crimes, being ostracized by a lot of people in school over her father, losing her friends who disowned her, blaming her mother for not knowing she married a monster and angry at Hartman and Vargas for arrested her father. She decided to reduced the charges while Angela accepts the plea deal in exchange to end things with her boyfriend and get treatment for her issues.
While speaking to Jack on the phone, she overheard the bank he and Lauren are in is being robbed and heads over there with her squad. Seeing Jack is wounded in a shootout with robbers, she speaks to the leader to trade her as a hostage in exchange for Jack and Lauren go free, but the leader refused to let Lauren go and instead offers her for Jack and a wounded colleague. After Hartman trading herself for Jack and the wounded suspect, Lauren uses her hairpin to remove the handcuffs off her as SWAT branched and Hartman wounded the leader before he can make his escape with a hostage. After dealing with some cases including a series of hate crimes against the LGBTQ+ community, Hartman sees the time she has with her family, especially her grandson Jason that makes her more happy.
After the escape of Angela's ex-boyfriend and other escape convicts which Hartman, the MCS and others were able to apprehend many of them (except for Angela's former boyfriend and two other escapees), she attended to the wedding of Ramsay and Grieco where she met up with former colleagues who were present at the wedding. Later on, Hartman, along with Ramsay and Vargas, worked with Denver Police Family Justice Unit detectives, including Drake Sullivan and his ADA wife Katherine, to shut down a criminal organization who sells abducted children to the highest bidder.
After wrapping up another case, Hartman received a distressing call from Jasmine that she and Max are in the shootout before she got shot. When she, along with Jack, the MCS and the other cops arrived, Hartman tried to tend to Jasmine, but Jasmine died on her arms, which the devastated Hartman cradled in her arms.
