Husband shoots dead his wife, nine-month-old son and three-year-old daughter before killing himself 'over money troubles after his holistic physiotherapy business collapsed' (11 Pics)

A family of four was killed in an apparent murder-suicide, according to police.

Jason Fairbanks, 39, Annie Fairbanks, 39, and their 3-year-old daughter and 9-month-old son died Friday afternoon, the Scottsdale Police Department said Saturday morning.

Jason Fairbanks shot and killed his wife and children in their home near Frank Lloyd Wright Boulevard and Thunderbird Road, said Sgt. Ben Hoster, Scottsdale Police Department spokesman. He then shot and killed himself.

The two-story stucco home is in a quiet upper-middle-class neighborhood. Homemade art adorned one of the family's windows. 

When Jason did not show up to work, a co-worker went to the home and discovered the bodies, Hoster said.

Hoster said the couple had been experiencing financial struggles. The two owned a Scottsdale business, Macrotherapy, specializing in physical therapy and rehabilitation. 

According to an event page, Annie Fairbanks was a Master CHEK Practitioner and a doctor of holistic nutrition.

Laura Fairbanks, Jason’s sister, described her older brother as a protector. She recalled a time when he was in college and flew home to drive her to school and calmly confront a boy who had been causing her problems. He then jumped back on a plane to school.

“He loved his family so much,” Laura Fairbanks said. “He wasn’t a bad person.”

She said he worked seven days a week to provide for his family. However, she knew that funds were not coming in like Jason needed them to.

Growing up, she said the two of them had a strong bond. Although he was a man of few words, she said she could always read between the lines and see how he was really feeling.

“I just wished he had asked for help,” she said. “Jason could make people laugh in ways you never thought you could. He was an extraordinary big brother.”

One of her favorite memories was when her father and Jason would visit her at the restaurant where she worked. She said the two of them would visit daily and make everyone around them laugh.

"They were closer than any father and son could be," Laura Fairbanks said. 

Laura described Annie Fairbanks as someone who was always smiling.

“When you were around her, she just made you feel all right,” she said. “It was just her presence.”

The murder-suicide took place Friday near 100th Street and Frank Lloyd Wright Boulevard Saturday in Scottsdale, Arizona, police confirmed

The couple had only been married for a year and a half, while the father's sister said, 'he loved his family so much'

She said Annie was very involved and loved her family.

"(Jason and Annie) moved in together, and a year and half later they were married," Laura said. "Boy, she loved those kids. She loved them so much."
