The brother, whose name was not released, grew suspicious after speaking with Terry at the hospital and contacted Chapmanville police.
Troopers interviewed Terry and his mother at the hospital. Terry's mother told troopers she did not see anything.
After several interviews Terry told officers he and his wife had an argument that escalated while they were in the motel room, Garren said.
He would not tell troopers what the argument was about but said he was defending himself when he pushed her away, causing her to fall and strike her head. Garren said Blankenship's injuries were consistent with a fall.
Garren said doctors performed several tests Sunday but found no brain activity. She was pronounced dead that evening.
Troopers at the Logan detachment weren't familiar with the couple, Garren said. Terry recently was released from prison after serving 14 months on a grand larceny conviction.
Terry was charged with first-degree murder. He is being held at Southwestern Regional Jail without bond.
