A Dalton woman was taken by helicopter to Sanford Hospital in Fargo on Saturday after her son allegedly attacked her with a machete, according to unofficial law enforcement scanner reports. The son was arrested this morning.

Barbara Howard, 68, was taken to Lake Region Hospital and then transported to Fargo after Otter Tail County sheriff’s deputies responded to a 911 call from her home at 7:50 p.m. on Saturday, according to the sheriff’s office. When deputies arrived at Howard’s home, they found her with a severe head injury caused by a “sharp-edged object.” The sheriff’s office has not released the kind of weapon used.

Deputies also found her son, James Howard, 46, also of Dalton, at the residence. James was suffering from a cut on his neck that he allegedly told deputies was self-inflicted. He also was taken to Lake Region Hospital.

After an investigation, the sheriff’s office arrested James for first degree assault today at 9:20 a.m. Attempted murder charges may also be pursued by the county attorney’s office.
