Chiefs linebacker Jovan Belcher spent part of the night at a woman's apartment and stayed until 6:30 a.m. on Saturday before going home, killing his longtime girlfriend and later himself, Kansas City police said Tuesday.

Police officers had contact with Belcher outside the woman's apartment building about 2:50 a.m. on Saturday after someone called 911 to report a suspicious car that had been in the parking lot for about two hours with its lights on.

Officers arrived at the building in the 700 block of Armour Boulevard, found the car, a black Bentley with temporary tags, and saw a man sleeping in the driver's seat. The officers knocked on the window, woke the man - later identified as Belcher - and asked him what he was doing. He told officers he was waiting for his girlfriend who lived in the building, said police spokesman Darin Snapp.

The officers asked Belcher to call his girlfriend and Belcher made a call from his cell phone, Snapp said. A short time later, a woman opened the apartment building door and let Belcher inside.

Police say the Kansas City Chiefs had been providing counseling to Belcher and his girlfriend, 22-year-old Kasandra Perkins, before last weekend's murder-suicide.

Police Sgt. Richard Sharp said that the couple had been arguing over relationship and financial issues for months and that the team had been "bending over backward" trying to help them.

Urlacher injured

With Brian Urlacher nursing a hamstring injury, the Chicago Bears have signed Dom DeCicco to a two-year contract, adding depth at linebacker.

Urlacher's status for this week's game at Minnesota and beyond is in question after he was injured on the final drive of Sunday's overtime loss to Seattle. Coach Lovie Smith said that he has a pulled hamstring.

The Chicago Tribune, citing sources, reported Tuesday that he is expected to miss three games and possibly the rest of the regular season.

Redskin suspended

Washington Redskins cornerback Cedric Griffin has been suspended four games without pay for violating the NFL's policy on performance enhancing substances.

He will miss the rest of the regular season and be eligible to return to the active roster on Dec. 31, following the team's Dec. 30 game against Dallas.
