The defendants, Clarence and Isabell Thayer, husband and wife, were tried jointly on indictments charging them with forcible rape of their two children,
2
both under the age of sixteen in violation of G. L. c. 265, § 22A (1992 ed.), and with indecent assault and battery on a child under the age of fourteen in violation of G. L. c. 265, § 13B (1992 ed.). After trial, the defendants were found guilty of statutory rape (G. L. c. 265, § 23) and indecent assault and battery. The defendants appealed to the Appeals Court which reversed the convictions of statutory rape and affirmed the convictions of indecent assault and battery.
From the evidence, the jury were warranted in finding that between December, 1985, and March, 1989, the defendants sexually abused their two children 3 by digital and penile, vaginal and anal, penetration.
*132 The children were removed from the defendants’ home by the Department of Social Services (department) in March, 1989, and in April were placed in the foster home of James and Janice Doran. They continued to see the defendants on a weekly basis under the supervision of a department social worker. After the girls disclosed to the Dorans in July and August, 1989, that Clarence had sexually abused them, the department terminated Clarence’s visitation rights. In late June, 1990, the girls told the Dorans and the department that their mother had also raped them.
1.
Lesser included offense.
Clarence concedes that statutory rape in G. L. c. 265, § 23,
4
is a lesser included offense within the forcible rape of a child under sixteen years of age within G. L. c. 265, § 22A.
Commonwealth
v.
Franks,
The test is whether on any view of the evidence a verdict of guilty of the lesser included offense of statutory rape is permitted. The test has been described in terms of whether the evidence presents “a rational basis for acquitting the defendant of the crime charged and convicting him of the lesser included offense.”
Commonwealth
v.
Santo,
This case is presented in a different focus from most cases involving the issue of an instruction on a lesser included offense because in most cases the defendant is arguing that the failure of the judge to give such instruction is reversible error. See, e.g.,
Commonwealth
v.
Campbell,
If the jury disbelieved the victims’ testimony about threats of slapping and spanking and getting in “trouble,” they might still believe that the defendants had intercourse with the victims or abused them. This hypothesis was sufficient to justify the instruction on statutory rape. 6
*134 For the first time, Clarence argues that he was deprived of the opportunity of arguing to the jury the crime of statutory rape. When he objected to the instruction, it was solely because in his view there was no evidence from which the jury could find the defendants guilty of statutory rape.
The Commonwealth concedes, as it must, that there was a violation of Mass. R. Crim. P. 24 (b),
Clarence was not prejudiced because he maintained throughout the case that the defendants never had sexual intercourse with the victims with or without force. This was Clarence’s position throughout the entire trial. He can hardly claim to be prejudiced by an instruction concerning rape without force.
2.
Fresh complaint.
Isabell argues that the victims’ statements to their foster parents in which they complain they were sexually abused by her, should not have been admitted as fresh complaint because of delay and coercion. These statements were uttered approximately sixteen months after the last alleged incident. There was no objection interposed at trial. There is no evidence that these statements were coerced and they were not untimely in the light of the victims’ ages and circumstances. See
Commonwealth
v.
Dockham,
3.
Expert testimony.
There was no error in qualifying a licensed psychiatric social worker as an expert witness. Her testimony did not exceed the province of her expertise and her competency did not depend on her being a medical doctor. See
Custody of a Minor (No. 2),
*135
4.
Other issues.
There was no error in denying the requested instruction on “missing witnesses” because a proper foundation had not been laid. There was no right to the instruction and the judge properly declined to provide it.
Commonwealth
v.
Franklin,
There is nothing to Isabell’s argument that the indictments were duplicative. Each indictment alleged a separate incident.
Judgments affirmed.
Notes
Pseudonyms are used. At the time the offenses began, Patty was six and one-half years old and Jill, four and one-half years old. Jill was the natural born child of the defendants. Patty is Isabell’s daughter and Clarence’s stepdaughter.
More graphic details can be found in the opinion of the Appeals Court,
General Laws c. 265, § 23, defines statutory rape as sexual intercourse or unnatural sexual intercourse and abuse of a child under sixteen years of age.
We see nothing in the Federal cases examined by the Appeals Court (
At oral argument Clarence argued for a rule by which we would be required to conclude that there was force simply because of the parent-child relationship. We are unable to find any such arguments in the brief. Mass. R. A. P. 16 (a) (4), as amended,
