A DEVASTATED Ipswich mum is today facing an agonising six-week wait to discover how her beloved six-year-old son suddenly died.

Little Jacob Gaecke died on December 21 - a year to the day after older sister Sarah, 15, was killed in a road accident.

A post mortem, which was carried out in the days after the latest tragedy, failed to find a cause of death.

Toxicology tests were ordered soon after - but police today confirmed the results will not be back until early February leaving heartbroken mum Vici waiting for answers.

A police investigation, launched immediately after Jacob's death, will not be concluded until the cause is established.

Currently, the death is being treated as unexplained.

Ambulance crews were called to Mrs Gaecke's Nacton Road home in the morning of December 21 but Jacob, who had severe physical disabilities, including cerebral palsy, was pronounced dead on their arrival.

Jacob's sister Sarah died three days after her 15th birthday on December 21, 2007.

She was a passenger in a car on A14 near the Orwell truck stop, when it was involved in a collision with another vehicle.

She managed to climb from the wreckage but was struck by another car and was killed instantly.

The car in which she was travelling was being driven by Samuel Clements who, it later emerged, was uninsured. Meanwhile, his vehicle was found to have a defective tyre.

Speaking to The Evening Star after Sarah's death, Mrs Gaecke revealed how close the teenager and Jacob had been.

“Sarah was a second carer to Jacob,” she said.

“She managed to care for her brother and also have a social life.

“Because of Sarah, there are a lot of people who now understand more about disabled children.

“She was very protective of Jake. She would defend him to the hilt.”
