An Indiana father, previously charged with murder and assault after defending his son from an aggressive crowd on a college campus, will not face prosecution.

On Tuesday, a grand jury in Franklin County, Kentucky, decided not to indict 48-year-old Jacob Bard, determining there was insufficient evidence to link him to the shooting incident at Kentucky State University (KSU). According to Bard’s lawyer, Jonathan Danks, this decision effectively closes the case, as reported by Law&Crime.

In October, a burglary occurred at a KSU dorm room belonging to one of Bard’s sons. According to Danks, the perpetrators—a coordinated group—pulled a fire alarm and used fire extinguishers to disable security cameras. The 18-year-old reported this crime to campus authorities.

Following the burglary, Bard’s son began receiving threats of violence, including death threats, as detailed by his attorney. Danks mentioned that one of the threatening students had previously had a firearm confiscated on campus but still boasted about possessing a gun.

On December 6, a group of 15-20 people, many of whom were not students and had concealed their identities, invaded the son’s dormitory, violently attacking him and three other students, according to Danks. The victims were reportedly thrown to the ground, repeatedly punched and kicked, and the attackers allegedly caused damage worth hundreds of dollars, including the destruction of a school laptop. The incident was documented by police and reportedly captured on camera.

Two days later, a larger group of 20-30 individuals, armed with baseball bats and other weapons, gathered outside the dorm. Danks noted that they banged on the door, prompting Bard’s son to call the police. The mob dispersed when officers arrived. That evening, Bard’s son informed his father about the unfolding events, Danks added.

Bard had two children who were currently attending KSU. He also had a 19-year-old son attending the university, and both teens were on the school’s baseball team.

The father and his wife “immediately” drove to the campus, arriving around midnight, and they realized that their son and his friends “had not eaten a meal in several days because they were afraid to leave their dorm rooms.” They took the young men to eat, and the next morning, the parents met with campus police to express their concerns.

The meeting did not sufficiently ease their concerns, Danks said, nor did a subsequent conversation with the university’s dean. The Bards “became convinced that the university would not be able to maintain a safe environment for their son and informed the university they were moving him home due to extreme safety concerns.”

Accompanied by a campus police officer, they approached the 18-year-old son’s dorm room to find four people outside “waiting for him,” Danks said. Though the officer ordered the group to leave, at one point, “one of the individuals involved in the prior assaults” began taking photographs of Bard’s sons. A physical confrontation was looming, and more and more people “involved in prior attacks” started arriving, some wearing ski masks, Danks reported.

“Watching the mob gather, Jacob Bard armed himself with his wife’s firearm,” Danks said. As the family and the officer escorting them reached the entrance to the building, “the mob immediately rushed out of the dormitory past an armed KSU police officer, and began violently assaulting Jacob’s family and others present.”

Bard and his family retreated about 40 feet, but they were being hit, and his son was “slammed into the concrete, and had multiple people on top of him beating his head against the pavement with feet and fists.” The officer was no help, according to Bard’s sequence of events.

“In the chaos, Jacob tried to physically pull the individuals off his son,” but he was hit and could not get the people off. Seeing him “in imminent danger of death and serious physical injury, Jacob then drew his firearm and shot two individuals who were actively and viciously beating his son.”

As Law&Crime previously reported, two people were struck by bullets. One of them, 19-year-old De’Jon Fox, died, while the other was taken to an area hospital in critical condition but later listed as stable.

After firing the gun, Bard “immediately dropped the weapon when his son was then able to escape the violence,” though not before being kicked in the face, Danks said. The attorney maintained that his client’s actions “were absolutely justified under the law, and were the only measure that prevented his son’s death or serious injury.”

Though Bard was charged with murder and assault, he and his legal team contended that the university was to blame for not addressing the previous alleged attacks. “Those failures ultimately resorted in the tragic death of one student and the injury of many others,” Danks said on Monday.

Danks also took issue with the mob of attackers not currently facing charges.

“Even now, despite the many known identities of students and others involved in the vicious attack that day and the multiple armed attacks in the days prior, criminal charges have not been pursued against those individuals,” Danks said.

“Jacob and his family continue to receive credible death threats, and Jacob’s sons are now residing in a non-disclosed location for their safety,” he continued.

According to local CBS affiliate WLKY, Bard will be repaid the bond he posted on Tuesday before the grand jury declined to indict him.

Franklin County Commonwealth Attorney Larry Cleveland suggested he was conflicted by the case. He told the outlet that he “felt that Mr. Bard could meet the requirements of defense of others, but at the same time, a young man was killed, and another young man was seriously injured.”

As part of a statement reported on by area Fox affiliate WDRB, KSU said it is cooperating with law enforcement as the investigation into the shooting continues.

“We remain centered on our students’ safety and well-being,” KSU President Koffi Akakpo, said. “The University is enhancing security measures and continuing internal reviews, while taking steps to help ensure our campus environment remains one where all can pursue their education safely. In accordance with University policies, when conduct within the University’s jurisdiction is found to violate our standards, appropriate action will be taken through established processes.”
