I'm not 100% convinced about that.
From the video:
WH: ...that person texted us and came out in little bits and pieces that she had used heroin for two weeks prior to her death. (4:41)
Reporter: What did the texts say?
WH: She texted my wife that information. My wife relayed information to me. She didn't tell me that information, Anjelica did not tell me directly that information but my wife told me that... she basically described a drug... and a reaction... it's physical, she's sick, she's in pain if she doesn't have it. This is what my wife told me. (5:03)
And from the article:
(WH) The text messages from Anjelica were saying that she used heroin two week prior to her disappearance.
Wait a minute. What text messages?
Oh you don`t know about those then. Anjelica texted us throughout the day of March 2nd after no one physically saw her after 2 pm I guess. Anjelicas phone communicated with my phone and her mothers phone. That`s why in the beginning I said that was not my daughter texting, someone had her phone. I can`t prove that, but that person texted us and came out in little bits and pieces that she had used heroin two weeks prior to her disappearance.

It really sounds like WH was saying that the person he and JH believe was impersonating AJ sent those texts on March 2. Oh how I wish WH would learn to speak in coherent sentences!
