"A source familiar with the situation said Hill's fiancee has been in contact with Overland Park police", the Star's Steve Vockrodt and Brooke Pryor reported.
Hill has not been charged with a crime. Espinal is named in the March 5 report under "others involved", according to the Kansas City Star.
Chiefs spokesman Ted Crews said Friday the team has been in contact with local authorities and the National Football League as it gathers more information but declined further comment. The source said that the incident was against the couple's son, resulting in a broken arm.
This is a very serious allegation especially given Hill's history of domestic violence.
In 2015, before Hill was drafted by the Chiefs, he pleaded guilty to domestic assault and battery in Oklahoma. The domestic violence conviction was dismissed and expunged from his record previous year after he completed his probation requirements.
"The club is aware of the investigation involving Tyreek Hill", the Chiefs said in a statement to The Star.More news: Spain investigates possible Central Intelligence Agency links to embassy break

The conviction was dismissed in August 2018 and ordered to be expunged after he completed his probation requirements.
He's just the latest Chiefs player to find himself in hot water. "We would never put anybody in this community in harm's way". We have things set up for him if there are issues, but he's been phenomenal.
It appeared to be working, too.
The two-time All-Pro had also positioned himself for a massive payday.
Last season he had 87 catches for 1,479 yards and 12 touchdowns. They advanced to the conference title game before losing in overtime the Super Bowl-champion Patriots.
In 2016, during his probation, Hill signed a four-year $2,586,220 contract with the Chiefs.
