I agree!
Here’s recap of the link for an appellant court ruling on use of a mannequin being acceptable and why the defense is on a highway to nowhere with the argument....IMO

Extract
It necessarily is vested with a broad discretion in admitting or rejecting such evidence. State v. Love, supra at p. 452.
Demonstrative evidence which tends to establish any fact in issue or throw light on the controversy and aid the jury in any way in arriving at a correct verdict is admissible within this rule, and if it accurately portrays the event or circumstances sought to be shown, it should not be rejected because by presenting an accurate portrayal it tends to be inflammatory. State v. Swenson, 551 S.W.2d 917, 921 (Mo.App.1977). Exhibit No. 4 admittedly was an accurate portrayal of the number and location of the stab wounds.
If the showing of their location and number tends to be inflammatory it is because any accurate portrayal, whether presented by oral testimony, or by a photograph, or as in this case by use of a paper maché mannequin, would be inflammatory. Notwithstanding its possible inflammatory nature, the exhibit met every test of probativeness. The exhibit visually demonstrated the nature and location of various wounds inflicted. State v. Jones, 515 S.W.2d 504, 506 (Mo.1974); State v. Wallace, 504 S.W.2d 67, 72 (Mo.1973); State v. Whiteaker, 499 S.W.2d 412, 418 (Mo.1973).
It also enabled the jury to better understand the facts elicited from the witnesses, State v. Crow, 486 S.W.2d 248, 256 (Mo. 1972); State v. Perkins, 382 S.W.2d 701, 704 (Mo.1964), and it corroborated the testimony of the State's witnesses. State v. Wallace, supra at p. 72, and State v. Jackson, 499 S.W.2d 467 (Mo.1973). In addition Exhibit 4 constituted demonstrative evidence which, if the jury determined that appellant perpetrated the homicide, would aid the jury in determining the intent with which the homicide was committed, and for that reason the jury was in a better position to determine whether appellant should be found guilty of capital murder, second degree murder, or manslaughter, all of which were the subject of an instruction to the jury.
The trial court did not abuse its discretion in admitting into evidence Exhibit No. 4, and in permitting its use as demonstrative evidence.
