The two athletes' friendship, which blossomed during their three seasons at the University of Illinois, was obvious to those who knew them. Milner said Brown was living with Brent during the six weeks he spent with the Cowboys.
"You can't get any tighter than those two," Milner said, crossing his index and middle fingers. "It was the closest family he had was Jerry Brown."
The circumstances surrounding Brown's death didn't change his family's view of his relationship with Brent, who pleaded guilty to a driving under the influence charge while a player at Illinois in 2009.
"I'm quite sure that Jerry thought the world of him and respected that young man," Clark said of Brent.
In the Illinois case, Brent was sentenced to 60 days in jail and two years of probation among other sanctions, court records show.
According to a probable cause affidavit released Sunday by Irving police, officers said they detected "a moderate odor of alcohol" from Brent's breath and that he "admitted to consuming alcohol at a club," but wouldn't identify which one. Police said Brent gave a blood sample at the hospital on Saturday.
Brown's mother, Stacey Jackson of Champaign, Ill., confirmed Brown's final Facebook post from Nov. 29, in which he wrote that he was expecting a child and "how the fast life isn't as fun as it use to be after living it for so long."
"She will be here in two more months," Jackson said of Brown's baby daughter. "She is going to be well loved. I have scrapbooks and everything to show her what type of father she had."
Clark saw Brown about four or five months ago, but spoke with him frequently via Facebook.
