A local psychologist accused of murdering his wife will appear in court for the first time early next week. 

Henderson homicide detectives compiled a highly detailed case against Dr. Brent Dennis in the 2015 death of his wife attorney Susan Winters, which was originally labeled a suicide.

The motive, police say, was pretty clear — money.

If not for a private investigation into winters’ death, there may not have been a murder case against her husband. Dr. Dennis stood to gain control of about $2 million when his wife died. The Winters’ family filed a civil lawsuit, which gave them the chance to question Dennis under oath.

The arrest report makes it clear that police relied heavily on the taped deposition because it revealed a number of discrepancies in the husband’s story.

The I-Team’s George Knapp was able to obtain the deposition and this is a heated exchange from that deposition which hasn’t been seen by the public.

When Dr. Brent Dennis goes on trial for murdering his wife, one of the key exhibits will be a check. It’s for $180,000, drawn from an account controlled solely by Susan Winters, not her husband. The signature is Susan’s, but it’s her husband who wrote out the amount. It also appears someone changed the date from 2014 to 2015. Attorneys for the Winters’ family say the check was  removed from the family checkbook six months before Susan died.

During a taped deposition of Brent Dennis, attorney Tony Sgro made a point of leaving a copy of the check on the table.

Transcript of deposition exchange:

Attorney Tony Sgro – “Now have you had a chance over the lunch break to re-examine the exhibit? Look at it a little more carefully?”

Brent Dennis: “I’m sorry I didn’t, no, I didn’t because it wasn’t in my instructions … is there a question?”

Sgro – “I asked if you over lunch break …”

Dennis – “No I did not.”

Sgro –  “Let me finish my questions, over the lunch break did you look at the exhibit?”

Dennis – “No.”

Sgro – “Now you understand that even though we say off the record there still a video feed that is continuously recording you?”

Dennis – “Oh, OK.”

Sgro – “Now let me ask you again, now that you’re aware that there’s video that continues to record, is it still your testimony that you didn’t look at the exhibit over the break?”

Dennis –  “I may have.” (laughing)

Sgro – “Sir, do you understand obligation to have to be truthful here?”

Dennis – “Nobody knew there were cameras … you had the grace to tell me that and I appreciate that.”

Sgro – “Now listen, cameras had nothing to do with you lying to me. Do you understand that, sir?”

Dennis – (laughing)

Sgro – “You think this is funny?”

Dennis –  “Oh my …”

Sgro – “Susan Winters is dead. You think this is funny?”

Dennis – “Sir.”

Sgro – “Do you think this is funny?”

Dennis – “No, I do not.”

Sgro –  “OK, now answer me truthfully. Did you look at that exhibit over the break?”

Dennis – “I possibly did.”

Sgro – “You possibly did? It happened 10 minutes ago. Did you look at exhibit or not?”

Dennis – “This, uh,  I possibly, I, uh …”

Sgro – “You did, didn’t you?”

Dennis – “I picked it up. Didn’t mean a looked at it.”

Sgro –  “Oh, so you picked it up. The funny thing is you didn’t tell me you picked it up or looked at it until I told you there was video that was continuing to roll, correct? Is that correct?”

Dennis – “I was under the impression of studying it for some reason and I was killing time.  I’m not sure what I was doing, you can …”

Sgro – “Now you don’t know what you’re doing 20 minutes ago? Did you do any drugs or alcohol in the lunch break?”

Dennis – “No.”

Sgro – “Is there any reason why your consciousness or state of mind would be altered over the lunch hour?”

Dennis – “No.”

Sgro – “So can you tell me, under oath, that you cannot recall what you were doing 20 minutes ago, is that your testimony?”

Dennis – “I don’t know specifically. If it’s on the tape, let’s play the tape. I …”

Sgro – “You understand we can’t follow you around with a video camera 24/7? You understand that? Sometimes we have to have the ability to rely on the things that you say. You get that?”

Dennis – “Yes.”

Sgro – “That’s part of this process here today.”

Dennis – “OK.”

Sgro – “So, with that predicate, what is your official answer as to whether not you reviewed the exhibit over the lunch hour?”

Dennis –  “I looked … I looked at it. I’m not sure what you mean by review.”

Sgro – “OK.”

After I asked him six or seven times, he finally said, OK, maybe I did look at something. It gives you in a microcosm, what kind of person this is. He strained to have any sort of relationship with the truth, Sgro said.

The exchange is telling, but here’s the real punchline. Hours before Susan Winters died, as she lay unconscious in her bed, dying from a lethal mix of pain pills and anti-freeze, her husband, according to police records, was downstairs on the phone trying to get information about how much money was in Winters’ bank account. Days later, he cased the suspicious check.
