NEW YORK -- Police have arrested the estranged husband of a young mother and nursing student who was found dead in her Long Island home earlier this month.
Michael Owen, a 27-year-old Marine, is charged with second-degree murder in the death of 27-year-old Kelly Owen.
Authorities say the two were estranged since January of 2019 and had a prior domestic incident in December of 2018, but they were still maintaining a physical relationship.
They believe he strangled her after she told him she was pregnant with their second child.
