Homicide investigator C.P. "Abbey" Abbondandolo of the Houston Police Department said the woman, whose identity was not released, claims not to remember any of her family members since suffering a blow to the head this month, the Houston Chronicle said Wednesday.
"It doesn't register with her at all," Abbondandolo said of the woman. "She is having a little trouble understanding all the things that have happened to her."
The woman entered a Houston hospital May 3 with injuries to her head and has since been released to an undisclosed location, police said.
Police suspect the woman may have been struck on the head, causing her apparent amnesia.
Abbondandolo told the Chronicle the woman is now struggling to come to terms with her apparent medical condition.
"What's happening now is she's trying to reacquaint herself with friends and family, which is difficult to say the least. That is a strange scenario to be in: 'I don't know who my parents are. I don't know who anybody else is,'" the detective said.
