A mother found dead with her two children in Darwin has been named by media as local veterinarian Jenny Wells.

Ms Wells, 46, was found about 50 metres from a house on a half-hectare block on Saturday morning by the property owner, who called ambulance and police.

The bodies of her 11-year-old son and seven-year-old daughter were found in a tent on the Jingili property.

Detective Acting Superintendent Lee Morgan of the NT Police says investigators are keeping an open mind about the cause of the deaths.

“We’re considering this could be a triple murder. We’re also very conscious of the fact it could be a double homicide and a suicide,” Supt Morgan said on Sunday.

Two knives found on the ground near the mother are being tested for DNA evidence.

The Nine Network said neighbours had described Ms Wells as friendly and easygoing with two great children.
