Jovan Belcher and Kasandra Perkins

In a surprising new development, Kansas City Chiefs linebacker Jovan Belcher cheated on his girlfriend the night before killing her and turning the gun on himself in front of his coach and general manager early Saturday.

The NY Post reports that the former Kansas City linebacker had a “boozy” dinner with another woman and spent the night in her apartment before he returned home, argued with Kasandra Perkins and shot her 9 times.

An unrepentant Brittni Glass admitted she dined with Belcher, 25, and shared alcoholic beverages with him at a local Tavern on Friday night. “I was with him that night, that’s it,” Glass told The Post yesterday.

After dinner, Belcher took Glass home, but he fell asleep in his Bentley outside her apartment, according to the woman’s neighbors.

Police rousted Belcher from his drunken stupor around 2:30 a.m., and he went inside Glass’s apartment. After spending the night with Glass, Belcher left at about 6:45 a.m. for the 10-minute drive to Perkins’ apartment.

The new developments conflict with the rosy picture painted by Belcher’s family and friends who say Belcher and Perkins were in love and never had any problems.

But a more clear picture of Belcher’s violent history is emerging. CBS’s Mike Freeman unearthed documents that show Belcher punched his fist through a window during an argument with a woman.

Freeman quoted a commenter on Deadspin.com who was an EMT at the University of Maine while Belcher was a student there in 2006. The commenter said Belcher “punched a window, the shards of glass cut his wrist, and completely severed his right thumb.”

Despite the commenters’ claim, the University campus police cited Belcher for simple criminal mischief. The report was filed under a misspelled name.
