The Larkville Police Department, is the primary responsible for law enforcement and investigation within the town of Larkville.
Shootout at the Tides Motel
Larkville Police Department was informed about the shootings at the Tides Motel. Police officers led by Roy Hardin arrived at the place where they discovered four dead bodies, and arrested Amy Bendix, Frank Castle and Marlena Olin. Three prisoners were taken to the Larkville County Sheriff Station, where Olin and Castle's wounds were treated by Evans. As the police were not sure what to do with the prisoners, Hardin decided to keep them at the station.
Upon Roy Hardin's order, Dobbs put prisoners' names and DNA samples into the system (Amy Bendix was identified as "Rachel" and Frank Castle as "Pete Castiglione"). Castle then exercised his right to a phone call and contacted Dinah Madani, however, she refused to help Castle. Hardin then questioned Castle about the people he killed at the Tides Motel, however, Castle stated that they will come for him and Bendix very soon.
Hardin ignored Castle's warnings and kept him at the station, placing him and Olin into the cells with Bruce Ogden, while Bendix was held as potential victim and witness. Later, police examined the identities of the prisoners and found information about Marlena Olin's service at the United States Army and her work as a private contractor, and Bendix's multiple identities. However, the identification systems were unable to find anything about Castle because his identity was perfectly clear.
Pressured by Hardin, Bendix confessed that Castle actually saved her from Olin and her subordinates, not kidnapped her as she previously stated. Hardin then visited Castle and Olin at their cells, telling them about the information the police found. Olin claimed that her people will not leave her at the cell and Hardin better to let her go what Hardin simply ignored, even when Castle confirmed her words.
Later, the station was visited by Ferrara and John Pilgrim. Ferrera stated that the state police sent him to pick up Hardin's prisoners on suspicion in drug trafficking. However, Hardin and Dobbs noted that he had no documents or official statements and refused to handle their prisoners to him, as they were not accused yet. While Hardin denied any Ferrara attempts to convince him, Pilgrim made a cryptic threat to him before leaving the station.
As soon as Ferrara and John Pilgrim left the Larkville County Sheriff Station, police officers had found out that the whole building was de-energized and all mobile and radio communications were jammed. Roy Hardin realized that the station was going to be attacked and ordered officers to prepare for a fight and try to reestablish their communications. Amy Bendix informed Hardin that Pilgrim and his men came for her and asked him to let her go what Hardin ignored once again.
Hardin ordered to bring Frank Castle at the office and demanded to tell everything that led in their current situations. Castle told Hardin and rest of the Larkville Police Department about the confrontation with mercenaries at Lola's Roadhouse and the Tides Motel, much to their disbelief. Castle attempted to convince Hardin to let them go once again, noting that Pilgrim's mercenaries will not stop until everyone at the station die.
Hardin refused to let the prisoners go and ordered Ken Ogden to drive away from the station and call the state police for help. As Hardin, Murphy and Dobbs covered Ogden from the inside, he reached the vehicle and attempted to drive. However, he was shot in the chest by Pilgrim before he could leave, and Hardin took him back to the station. Pilgrim noted that Hardin will survive only with medical assistance, and Hardin has to give prisoners to him or every officer in the building will die.
While Murphy, Dobbs, and Bendix were treating Ogden's wound, the station was attacked by Pilgrim's mercenaries. Hardin and the officers attempted to fight back, however, several hostiles bypassed the crossfire and broke into the building. As they released Marlena Olin from her cell, they attempted to kill the officers. However, Castle managed to free himself and quickly take down every single mercenary in the station, saving the officers.
Having a brief pause, Hardin figured that that was only first wave before the larger attack. Reluctantly, Hardin allowed Castle to deal with the mercenaries outside of the station. Much to their shock, Hardin and other police officers witnessed Castle shooting down every single hostile by himself.
As most of them were killed by Castle, the Homeland Security had arrived to assist the Larkville Police Department. Homeland Security provided paramedics to provide medical support for Ogden and deal with the aftermath of the attack. Dinah Madani personally asked Hardin to allow Castle to go with her and keep his involvement in secret what Hardin accepted. Returning Castle his property, he allowed him and Bendix to leave Ohio with Madani.
