An Oregon mother who suffered a mental breakdown while caring for her autistic son and husband with Multiple Sclerosis allegedly threw her 6-year-old off the Yaquina Bridge Monday and then called 911 to report the incident, reports NBC News.

Jillian Meredith McCabe, 34, was charged with murdering her son, London, and arrested.

The Coast Guard said that London's body was recovered early Tuesday after someone at the Embarcadero Resort restaurant a mile away spotted a body in the water, reports the Oregonian. The Coast Guard and fire department converged on the location.

"The fire department got there first and recovered the body," Coast Guard spokesman told NBC News. "It's absolutely a tragedy."

According to the Newport Police Department, Jillian was located near the bridge, interviewed, and subsequently arrested for aggravated murder, murder and 1st degree manslaughter. Her bail was set at $750,000.

Andrew McCabe, London's uncle, said that Jillian took London for a walk and then threw him off the bridge. He believes a lack of adequate mental health services contributed to the tragedy.

"The state of health care in the country and the lack of prioritization that we have especially for our mentally ill is appalling. And it's heartbreaking and unfortunately there's tragic results when people don't get the help they need," he said.

Relatives claim the tremendous stress of caring for an autistic child and a husband diagnosed with MS and a mass in the brain stem, plus coping with the death of her father, led the once-stable mother to a mental collapse. In addition, her husband, Matt McCabe, had been the family's only source of income.

Tanya McCabe, London's great-aunt, said the family obtained psychiatric services for Jillian that included inpatient care. Jillian had talked about harming herself, Tanya confirmed, but the family never thought she would harm or kill her son.

"Jillian was always so patient with him, and loving. She really had a lot of compassion for his condition. When he was screaming at the top of his lungs, which was the only way he could communicate, she didn't get upset at all. She would calmly comfort him, and I was amazed at how patient she was," Tanya said. "So this was shocking and heartbreaking."
