It was a day much like this one. Calm. Quiet.

Neighbors say they said hello Monday afternoon to 32-year-old Jason Cook.

Then, night fell, and their neighbor's life did too.

"I kinda freaked out, I saw ambulances, cop cars, I didn't know what was going on," says neighbor Chris Brown.

"We're treating this investigation as a homicide," says Lt. Noel Garcia of the Lansing Police Department.

Garcia says Cook's lifeless body was found by a relative inside his house on the 200 block of West Barnes Ave. around 9:30 p.m. Monday.

Family members asked we not videotape them as they moved Cook's belongings out of his duplex Tuesday. A man sat on Cook's stoop with his head in his hands-- overcome with emotion at the loss of the young man.

"Right now we're in the process of gathering information," Garcia says, saying they're trying to focus their investigation on a suspect or suspects but not having luck yet.

Unlike other homicide investigations this year, police say they have little to go on, and that they say will prove to be the biggest challenge.

"Usually we get a good momentum started, but we haven't gotten that this time," Garcia says. "Because we have limited information, that's why we're reaching out [to the public]."

But reaching out might prove difficult-- most neighbors are hesitant to talk. Others, like Chris Brown, don't have much to offer.

"I haven't heard anything from anybody," says Brown.

"Anything suspicious at all, if they had any contact with people at that residence in the past few days, it's important to come forward," Garcia says. "It's crucial. It may be, it may not be, but it could be a piece of the puzzle we need to put together to find out who's responsible."

Police say, however, the crime does not appear to be random, though they urge people to stay on alert. Please call Lansing police if you have any tips on this murder: 483-4600 or 272-7485.
