A 51-year-old man was arrested Monday evening in connection with a fatal shooting after his teenage son escaped their Caldwell home and called police.
Delbert Cornish was arrested Monday on multiple charges after a woman was found dead in a home on Blaine Street. The Canyon County Coroner identified the woman as 18-year-old Hope Cornish on Tuesday.
Delbert is Hope’s non-biological father, a Caldwell Police spokesperson told KTVB.
The incident began shortly after 4 p.m. Monday, Aug. 18, when the teen called 911 to report that his father was armed inside their home. The son told dispatchers he found Cornish with a gun when he arrived home, according to the Caldwell Police Department (CPD).
Police said the teen reported that Cornish had made threats about shooting a family member and tried to prevent him from leaving. The son escaped after a brief struggle and called for help. CPD officers established a perimeter around the residence and spoke with the son outside.
When officers later entered the home, they found a deceased woman, now identified as Hope. “Police also recovered a firearm at the scene.
The suspect, Debert, was arrested by Mountain Home police officers after they tracked him using Automated License Plate Reader cameras. Police said he was taken into custody without incident around 7:30 p.m. Monday.
Delbert was booked in the Elmore County Jail on a murder charge and an attempted murder charge. He was later booked into the Canyon County jail on a murder charge and aggravated assault.
The case remains under investigation.
Monday’s response involved multiple agencies, including the Canyon County Sheriff’s Office, Elmore County Sheriff’s Office, Nampa Police Department K9 unit and Mountain Home Police Department.
