In new court docs, Josiah Kassahun's estate claims Kennedy beat the hell out of Kassahun at a Comfort Suites in Illinois on July 27, and did nothing to help him afterward.

Kassahun's family says Kennedy hit Kassahun, which caused him to fall to the ground and land on his head.

The family goes on to say in the docs that Kennedy kept hitting Kassahun while he was on the ground, and then did not get him medical attention after he had finished the attack.

Kassahun's family says Kassahun later died on July 31 from injuries he suffered in the altercation.

The estate is suing Kennedy and says the damages exceed $50,000, the docs show.

As we previously reported, Kennedy was charged with first-degree murder on Monday over the alleged incident.

In charging docs, prosecutors say Kennedy punched Kassahun in the head, and then kicked him in the torso while he was on the ground. They claim the strikes ultimately led to Kassahun's death.

Kennedy could face up to life behind bars if convicted.

It's still unclear why Kennedy allegedly attacked Kassahun, though social media postings appear to show Kassahun and Kennedy were friends at one time.

Jail records show 36-year-old Kennedy is still behind bars.
