A Boulder woman is suspected of killing her two-month-old son after disappearing with the baby for several hours Saturday, according to Boulder police.

Anna Englund, 29, was arrested for investigation of first-degree murder and child abuse that recklessly caused death after her son died at Boulder Community Hospital on Saturday night, according to police and jail records.

Hours earlier, Boulder police officers were asked to conduct a welfare check on the woman because she may have been having a mental health crisis, according to a news release.

She was gone from her home in north Boulder by the time police conducted the check at about 4:30 p.m., and witnesses told officers she had gotten in her car and and driven away with the baby, police said.

Boulder police officers then issued a statewide “attempt to locate” bulletin for Englund and the infant. Several hours later, about 10:20 p.m., officers spotted Englund’s car as she drove to Boulder Community Hospital. Officers met her in the hospital parking lot, according to a news release.

The officers rushed the baby into the emergency room, where he was declared dead at 10:48 p.m., police said in the news release. A police spokeswoman, Jennifer Ciplet, could not say Sunday how the baby died or whether the infant suffered visible injuries. She said Englund was “en route” to the hospital when she was spotted by police.

The child’s cause and manner of death will be determined by the Boulder County coroner.

Englund was booked into the county jail at 5:43 a.m. Sunday, according to online jail booking reports. She has no other criminal history in Colorado, according to court records and the Colorado Bureau of Investigation.
