CBS 12 Exclusive: Why did Wellington dad snap?

The father, a former mortgage broker and board member of the Jewish Community Center. His wife, an aspiring children's book author. Their twin boys planned on having a party for their seventh birthday today. The picture perfect family lived in this giant home, it's a neighborhood where people drive nice cars, but behind closed doors it can be a different story.

"The loveliest people, loving and the loveliest people," said Dr. Henry Katz, a family friend.

Early this morning deputies say 49-year-old Neal Jacobson went on a killing spree. His wife Franki and their twin sons Josh and Eric, shot and killed in their home here on South Sea Court. The twins just turned 7 years old this week.

Dr. Katz said, "if they told me he was father of the year I would have believed them, it's overwhelming."

It all started when a Jacobson crashed his SUV shortly after 7 o'clock this morning here on Atlantic Avenue in Delray Beach. With bloody hands and ammunition sitting next to him, authorities say he confessed to the unthinkable.

A spokesman with the Palm Beach County Sheriff's Office said, "The subject told paramedics he had killed his family."

Deputies raced to the home and found the mom and the two children dead inside.

Linda Katz said, "Something snapped, maybe the pressures of the economy, something caused Neil to snap."

Dr. Katz said, "I know he was always into grandiose financial transactions such as mining gold in China."

Now these crime scene investigators and family friends are united, all set on answering the one big question, why? Investigators believe Jacobson also tried to take this own life. Reports show that he admitted to taking 10 Xanax pills. He was first taken to Delray medical center with injuries from the crash. According to data from the sheriff's office, he was booked at 5:30 this evening for the murders.
