"I've just snapped. I can't take this meaningless existence anymore I've been a constant disappointment and that trend would have only continued."
Hawkins added, "I love you mommy. I love you dad," and expressed love for several other people. He told them to remember the good times they had.
"Just think tho I'm gonna be (expletive) famous," he wrote.
Also Friday, those who knew Hawkins most recently in suburban Bellevue said they tried to warn police about his behavior but got no response.
A man who lived nearby said he went to police a month ago to report his and other parents' concerns that Hawkins and his friends had easy access to guns, sold drugs and smoked pot with an adult.
Bellevue police said the house where Hawkins lived is in an unincorporated part of the city and not in their jurisdiction. Police Chief John Stacey would not talk about Kevin Harrington's complaint, but said normally officers pass complaints from that neighborhood onto the Sarpy County Sheriff.
Sheriff's officials said they never received the complaint.
Harrington, 45, said he told police in Bellevue about a month ago that one of Hawkins' friends offered to sell Valium to his 13-year-old son. Harrington said he also told police that Hawkins had previously shot at a car during a drug deal gone bad.
"We told them about the drugs, we told them about the guns, and nothing was done," Harrington said.
Harrington said his 16-year-old daughter used to hang out with the group of teens in the neighborhood at the home of Debora Maruca-Kovac, the 50-year-old woman Hawkins lived with.
Maruca-Kovac told the Omaha World-Herald that Hawkins showed her a rifle on Tuesday, but that she thought it was too old to work.
Harrington said he wished someone had listened to the warnings.
He called police again Thursday after his daughter got a phone call from Hawkins' best friend, 17-year-old David Horvath.
After the shootings, Horvath left Shelby Harrington a voicemail message, threatening to "cap" her if she didn't stop saying bad things about Hawkins, Harrington said.
Shelby Harrington had posted a critical comment about Hawkins on an Internet site after some of Hawkins' friends defended him. Horvath was charged Friday in Sarpy County Court with intimidation by phone call.
And Thursday evening, while his daughter was filming an interview with TV's "Good Morning America," she got a threatening text message from another friend of Hawkins. A 16-year-old boy was cited for disturbing the peace in that incident, Bellevue police said.
