YAKIMA, Wash. — The pregnant Terrace Heights woman shot by her husband last week died Wednesday.

Yakima County Coroner Jack Hawkins said 27-year-old McKaylee Higgs had been on life support and died Wednesday evening at Yakima Regional Medical and Cardiac Center after she was taken off a respirator.

Hawkins said an autopsy Thursday confirmed Higgs had been fatally wounded by a gunshot wound to the neck that caused severe damage to her spinal cord and a dangerous buildup of fluid on the brain.

He said Higgs was never conscious and that doctors said her injuries had caused severe and irreparable brain damage. He also confirmed that Higgs was about 10 weeks pregnant. The fetus also died.

Sheriff’s deputies have said Higgs’ husband, 25-year-old Cory Lindblom, shot his wife in the bedroom of their duplex on Nola Loop after he mistook her for an intruder.

Earlier this week, Chief of Detectives Stew Graham said he had not uncovered evidence of criminal intent and that, absent new and incriminating evidence, detectives planned to refer the case to prosecutors for further disposition.

Graham suggested Lindblom could face a charge of reckless endangerment or criminally negligent homicide, but that such a decision would be left to prosecutors.

Graham declined to elaborate on the scenario as described by Lindblom that would explain why he opened fire on his wife in her own bedroom, and neither he nor several other sheriff’s officials returned calls Thursday on the status of the investigation.

Hawkins, the coroner, said surgeons previously recovered a 9 mm bullet that had lodged in Higgs’ shoulder.
