Delicia Cordon, the ex-girlfriend of Buffalo Bills running back LeSean McCoy, reiterated in a news conference Friday that she believes McCoy was involved in an assault and robbery against her in July.

“The LeSean McCoy that I know behind closed doors is different than the LeSean McCoy in front of the cameras," Cordon said. "This attack was about the jewelry that LeSean expressed he wanted back from me weeks before the attack.”

Cordon also announced that she would be doubling the reward offered Thursday for any information related to the case, with the amount now sitting at $40,000.

An assailant allegedly broke into a Georgia home owned by McCoy on July 10, brandishing a pistol and demanding specific items of jewelry. According to a 14-page complaint Cordon filed in the State Court of Fulton County in August against McCoy, the jewelry was worth $133,000.

“Every day I live my life in fear, not knowing if I’m walking past the man who savagely attacked me,” Cordon said. “It is unfair that I have to be afraid to do normal things like grocery shop. I have panic attacks. I can’t sleep at night, I can’t. I don’t feel comfort protecting my children. I have my daughter sleep in the bed with me every night. LeSean said that he was going to deal with all of this after his season. I don’t have that option. I have to deal with this every day.

“He’s not helping. He’s not giving up any information with the security cameras that we have asked. He simply is – I don’t know. I don’t know what he’s doing. I am afraid for my children. I am afraid that the intruder will attempt to take the remaining items that were demanded, but did not collect.”

'Ridiculous':McCoy says child abuse allegations are false

Tanya Mitchell Graham, Cordon’s attorney, said that the NFL, which announced shortly after the assault became public that it would be investigating the incident, has not reached out to Cordon.

McCoy has repeatedly denied any involvement with the incident. On Tuesday, the mother of McCoy’s son, Stephanie Maisonet, provided an affidavit that was included in the civil case Cordon filed that alleges their son would “often come home with bruises” after spending time with McCoy. In order to explain the bruises, Maisonet said she would “consistently receive outlandish excuses” from McCoy.

On Tuesday, McCoy released a statement, again denying any wrongdoing.

“The allegations made against me today regarding my relationship with my son are provably false, outrageously inaccurate and offensive,” McCoy said in the statement. “I have a loving and close knit relationship with my son. That young boy is my while life. With a custody case coming up in November , I can see why these false allegations are surfacing.”

Cordon said other women, in addition to Maisonet, have contacted her to allege McCoy had “physically abused them, taken back other gifts he has given them, and exhibited aggressive behavior towards them and towards his child.”
