KANSAS CITY, Mo. —
York said that sometime after Halloween Perkins had gone to visit her family in Texas. Perkins also briefly stayed with her cousin, who is married to Chiefs player Jamaal Charles. Belcher and Perkins met through Charles, York said.
A message left for Charles and his wife through an assistant was not immediately returned.
York said the root of the argument was that Belcher, "sometimes he would just be down in his man cave or whatever," and Perkins wanted to spend more time together as a family.
"They ended up wanting to try to work it out," York said, "and the next time I went over and visited she told me everything was good and things were better, so I thought everything was fine."
Kansas City police spokesman Darin Snapp reiterated Sunday that the couple had argued recently but he could provide no additional details.
At the couple's former home, people could be seen coming and going Sunday. "Can you all respect grieving?" said a man who answered the door at the couple's home. A short time later, at the same time the Chiefs were playing, two men loaded bags into a car, and two women drove away.
Attempts to reach various members of Perkins' family in Austin, Texas, were unsuccessful.
Neighbors in the newly built Kansas City subdivision where the couple had lived since April were stunned by Saturday's violent events.
Kristen VanMeter, 31, lives near the couple and said also she had taken community-college courses with Perkins. VanMeter said the couple threw "a lot of parties" but said she heard nothing unusual the morning of the killing.
"It's a surprise," she said. "There had to of been something that triggered it."
