A Tennessee police officer has been indicted by a federal grand jury following allegations that he assaulted his estranged girlfriend, vandalized her possessions, and threatened her life — all while on duty.

Alan James Greenman, who was serving as a patrolman for the Clarksville Police Department at the time, faces charges of kidnapping, stalking, and violating rights in relation to the incident on August 20. According to a probable cause affidavit, the 38-year-old officer began his shift shortly after 5:30 a.m. and accessed the apartment complex where his girlfriend lived multiple times using a gate code intended for utility companies, which the general public cannot use.

The girlfriend provided a statement to investigators saying she returned home at approximately 6:30 a.m. to find Greenman waiting outside her door. Though they had been in a relationship, they were on a break, and she had previously given him a key to her apartment with the understanding that he would return it. Their argument began when Greenman accused her of infidelity and demanded to inspect her phone, as described in the complaint.

The dispute continued into her bedroom, where Greenman allegedly used a screwdriver to repeatedly stab the television mounted on the wall. She then urged him to leave.

“She told him that ‘this isn’t worth your job or mine.’ [The victim] told Greenman that he was scaring her,” the affidavit detailed. “She feared he would stab her.”

The argument continued to escalate, the affidavit alleges. As Greenman wore his police uniform, which included his bulletproof vest and duty belt, he began wrestling with the victim for her cellphones, federal agents said.

“She described herself as hysterically crying and pleading with him not to break her personal cell phone and to give it back to her, as that was her only means of getting in touch with her kids. She also described begging him to leave,” the complaint stated.

Greenman allegedly ended up breaking her personal cellphone. When she tried to leave, he allegedly threw her across the room onto the bed. He then allegedly took out his service weapon and pointed it at her, telling her “I’m going to f—ing kill you.”

All of this occurred as her 4-year-old son was sleeping in the next room, according to the affidavit.

The victim said she begged for her life and told him that she is the mother to four kids. Greenman broke several other items in the bedroom, including a gaming headset and controller, the affidavit said. Eventually, the victim escaped the bedroom, grabbed her young son, and ran to a friend’s house. She alerted Greenman’s chain of command about the incident.

After the incident, Greenman apparently went back to his patrol car where his dashcam captured a phone call with an unknown man. He indicated he was contemplating suicide, according to the affidavit.

“Everything is way past being fixed because I broke all her s—, I broke all her s—, her phone,” Greenman allegedly said. “She was crying like crazy. I f—ing attacked her multiple times, pulled a gun on her, like there’s no coming back from any of this.”

Cops found Greenman in a closet in the woman’s apartment holding a gun, per the complaint.

After being read his Miranda rights, Greenman allegedly admitted to threatening his girlfriend and breaking some of her personal items but denied pointing his service weapon at her or pulling it out of his holster. Detectives noted that there is a sensor on Greenman’s holster that activates the dashcam on his cruiser. The camera activated around the time of the alleged assault, which investigators say backed up the victim’s claims.

Greenman is also facing state aggravated assault domestic violence and kidnapping charges, according to the Tennessee Bureau of Investigation.

Clarksville Now reports that Greenman was fired from the department on Sept. 5.

“The actions of Mr. Greenman are not reflective of the values or professionalism of this department,” the agency said in a statement to the outlet. “The reputation of the Clarksville Police Department and the trust of our community are of the utmost importance. We are committed to transparency and to holding all employees – sworn and civilian – accountable both administratively and criminally, when necessary.”
