Stephen Angelo Simpson, Jennifer Hudson's half-brother, was arrested yesterday (Aug. 19) for allegedly stabbing his estranged wife's boyfriend in South Haven Charter Township, Mich.

According to WWMT, Simpson went to his estranged wife's apartment, where he stabbed Charlie (her beau was only identified by first name) repeatedly after he answered the door on Monday (Aug. 18).

"I open the door and see blood everywhere," Torrey Hunt, the neighbor that helped Charlie, told WWMT. "He was stabbed in his chin and his chest, he had puncture wounds in his chest and his arms and stuff."

According to authorities, the victim had several stab wounds on the face. Simpson's wife hid in the bathroom while he stabbed her boyfriend.

Simpson, who has a history of domestic violence, is currently on probation for multiple arrests, one of which includes assaulting his wife on Super Bowl Sunday.

Charlie came out of the situation with 20 to 30 stitches and was then released. Meanwhile, Simpson will likely be charged today (Aug. 20) for first degree home invasion and attempted murder.
