KANSAS CITY, Mo. -- NFL linebacker Jovan Belcher displayed "no major issues" in his personal life before he killed his girlfriend and then shot himself to death for no apparent reason, Kansas City Chiefs head coach Romeo Crennel told a news conference today.

"I'm not a psychologist, I don't know what made him snap," Crennel, who witnessed the suicide at the team's practice facility, said. "I was surprised."

Crennel said there are "counselors on site and they'll be here most of the week."

Two days after Belcher killed the mother of his 3-month-old baby, shooting the woman multiple times, police say, details about what led to the murder-suicide remain sketchy.

Belcher's emotional teammates defeated the Carolina Panthers 27-21 Sunday in a game overshadowed by Saturday's tragic developments, as Belcher's No. 59 jersey remained hanging in his locker.

"It was tough," fellow Chiefs linebacker Andy Studebaker said. "You miss him, you know. He was a great guy and a great teammate. We loved his family and, like I said, my heart goes out to them. Our prayers are with the family. But it was tough not having him here today and it's not easy, but we miss him."

In a statement today, the family of Kassandra "Kasi" Perkins said:

"On behalf of the Perkins Family, we appreciate the outpouring of love and concern for our Kassandra "Kasi" Perkins. Our hearts are truly broken for Kasi was a beloved daughter, granddaughter, sister, mother, cousin and friend. At this time we request the media respect our privacy during this difficult time as we grieve for our loved one. Please keep us in your hearts and prayers as well as the Belcher family for two lives were loss [sic]."

Belcher's family, through aunt Mary Kimble, also issued a statement.

"We can't express the sorrow we feel over the loss of Javon and Kassandra," it read. "The impact that this inconceivable tragedy has had on our hearts is immeasurable. We are overwhelmed with both sadness and confusion. Javon was our son, brother, uncle, cousin, nephew, grandson and friend and we will miss him and Kassandra daily. Our thoughts and prayers are with the Perkins family as well as they mourn."

More than a year before the shooting, Belcher, 25, and Perkins, 22, had apparently enjoyed spending time together at a gun range, a friend of Kassandra Perkins said.

"I know that before she was pregnant, that they liked to go to the gun range and shoot and that it was a lot of fun for them," Brianne York told ABC News. "I just asked her if, 'You know it was fun to learn how to shoot,' and they would go to the range and do it and she just told me, "Yeah."

Belcher was comfortable using a gun and kept some at his house, York added.

"They'd fight and you know be mad at each other and then they'd talk it over and they'd move on and be happy again," York said. "He seemed really happy to me. He never showed any signs that he didn't want a baby. He seemed to be happy that he was having [one] and starting his own little family.

She added: "He was just so calm and collected and laid back and he was fun to be around and she was. too. and I just never would have imagined that he would do something like this."
