Two fired cartridge casings, a police backpack and vest and a metal marijuana grinder were some of the other items recovered from Jean's apartment following the search warrant. The Dallas Police Department could not be immediately reached for comment regarding the search warrants.
Another attorney for the family, Daryl Washington, added, "It doesn't change the story".
After reading the affidavit, association staff attorney Shannon Edmonds said the documents indicate police knew what was in the apartment before they asked the judge to search the residence.
David Menschel, an Oregon-based criminal defense attorney and activist, called the release of the search warrant "propaganda".
"The main problem is: What was Officer Guyger doing in Jean's apartment in the first place?"
Dallas mayor Mike Rawlings and Dallas Police Chief U. Renee Hall are in attendance at the funeral.
But then around 5 p.m., the family's lawyers were alerted to some apparent breaking news in the investigation into Jean's death. Botham Jean was killed in his own home and his life matters. She claimed she saw a "large silhouette" from across the room, believed it was a burglar and fired her gun twice, striking him in the torso and killing him, the arrest affidavit states.More news: What impact will Trump's new tariffs on China have?

The arrest warrant for Guyger, written by Texas Rangers Officer David L. Armstrong, claimed that the officer used her electronic key to attempt to open the door, and the door opened because it was ajar.
O'Donnell said it would require a full investigation to determine all the factors that went into her shooting Jean, and that one or two details could make a difference. Police allegedly found little more than 10 ounces. He said a search warrant can help avoid a situation where there's a question of whether investigators had authority to search a residence.
This is clearly a tactic to criminalize the victim, which we have seen happen constantly, from Trayvon Martin to Tamir Rice. "And instead of investigating the homicide - instead of going into her apartment and seeing what they can find, instead of collecting evidence relevant for the homicide investigation - they went out specifically looking for ways to tarnish the image of this young man".
The warrants also show that photographs, videos and laser measurements of firearm trajectory were taken in Jean's apartment and gunshot residue from his apartment's door frame and kitchen wall were collected, the WFAA story said.
On Friday, Jean's family addressed the new developments in a press conference.
"The information released yesterday, was worse than the call I received last Friday", said Jean's mother, Allister Jean.
Authorities have not said whether Guyger's apartment or vehicle were searched. "It's just good police work".
