A Clarksville woman has died after an attack inside her home over the weekend. Ethel Adamson's son called police Sunday just after 9 a.m. to report his mother was unresponsive and had an injury to her head inside her home in the 700 block of Central Avenue. Adamson, 60, was airlifted to Vanderbilt University Medical Center where she remained in critical condition until her death Tuesday afternoon. "She was a very friendly woman and very considerate of others," Adamson's neighbor Jerri Willhite said. "She and I talked every day."She continued, "It hurts bad."Clarksville police are investigating Adamson's death as a homicide, which the department said is common procedure when there is an unattended death. However, early on the department treated the case as an aggravated assault because of Adamson's injuries. There were no signs of forced entry to the home. Neighbors reported hearing someone enter the home around 1 a.m. Sunday but, nothing out of the ordinary after that time. "I didn't hear her scream and I didn't hear yelling," Willhite said. "It really makes me wonder who did this."Her son reported leaving the house at around midnight and locking the door.According to police, he said when he returned home Sunday morning he found the door unlocked.Adamson's son declined to comment when reached by Nashville's News 2. He asked for privacy as he and his family grieved for his mother. "I am really concerned that something is going to happen to me now I am really scared," she said.
