A police report released to Fox News Digital on Thursday revealed more details in the death of actor Jansen Panettiere, the 28-year-old brother of actress Hayden Panettiere.

The Orangetown Police Department's initial report from the scene showed officers responded to Panettiere's apartment in Nyack, New York, shortly after 5 p.m. Sunday on report of an "unresponsive male with CPR in progress." 

When officers arrived at the home, Benjamin Brown, a friend of Panettiere, was performing CPR on the actor, who was laying on his back on the living room floor. Panettiere was reportedly not breathing and was cold to the touch with lividity. He was pronounced dead at 5:11 p.m. by a responding EMT.

Brown told first responders he and Panettiere were supposed to meet for business purposes, but when the actor did not show up to the meeting, Brown became concerned and went to his apartment.

When he got to the apartment, he saw Panettiere unresponsive and sitting upright in a chair. Brown then called 911.

The report said Panettiere's father, Alan, also responded to the scene and said he spoke to his son, who "sounded okay," the night before on the telephone.

Following those details, about five lines of the report were redacted and not available.
