Shanon Thomas was convicted of first-degree murder in violation of 18 U.S.C. §§ 1111, 113, and 1153, and sentenced to life imprisonment. He appeals from his conviction, arguing that the district court 1 erred in denying his motion to suppress, his motion for judgment of acquittal, and his motion for a mistrial. We affirm.
I.
On the evening of April 17, 2010, Thomas and his girlfriend, Marissa Mackey, found that Mackey’s residence had been vandalized. They suspected that Dawn Starlin, Mackey’s neighbor across the back alley and Thomas’s former girlfriend, was the culprit. After discovering the vandalism, Thomas retrieved a gun from his sister’s residence and left it behind Mackey’s home. Thomas and Mackey then went out to a bar with some friends. When they returned home Thomas went outside, and Starlin, who was sitting in a chair in her backyard, began taunting him about his relationship with Mackey. Thomas retrieved the gun he had left earlier that evening, walked towards Starlin, and shot her multiple times. Starlin was found dead outside her home early in the morning on April 18, 2010.
Around four o’clock that afternoon, Thomas requested that the officers investigating Starlin’s death come to his mother’s home to speak with him. Upon arrival, the officers saw Thomas hugging his mother, who was crying. Thomas waved the officers inside. When the officers entered the house Thomas acted as though he expected to leave with them, saying “let’s go,” and stepping towards them. Officer Grunder then asked Thomas why he did “it” and whether he had been drinking. Thomas responded only that he had not been drinking. Grunder next asked Thomas where he had gotten the gun, Thomas replied that he had obtained it *221 earlier the night of April 17th. Grander asked where the gun was, to which Thomas replied that it was gone and that he “didn’t mean to gun her down.” Grander testified that he thought he had enough probable cause to arrest Thomas after the last statement. Thomas was not advised of his Miranda rights before this conversation, which lasted only a minute or two. Thomas was placed under arrest and taken from his mother’s home to the police station, where, after being advised of his Miranda rights, he made a full confession. The following day, at the Dakota County Jail, Thomas was again informed of his Miranda rights and interviewed, and he confessed again.
Before trial, Thomas moved to suppress evidence of the conversation that occurred at his mother’s house, as well as his subsequent statements at the police station-and jail. The district court denied the motion, finding that the statements made at the house were made in a non-custodial setting and that Thomas was informed of and waived his Miranda rights before making in-custody confessions.
The trial focused on Thomas’s mental state at the time of the shooting. The jury was presented with the evidence of Thomas’s confessions through the testimony of the FBI agents who had investigated the case. Additionally, Justina Tuttle and Waylon Wabasha testified that they had been socializing with Thomas and Mackey on the evening of April 17th. Tuttle and Wabasha both testified that Thomas had left Mackey’s house and returned a few minutes later with a gun. Later in the evening, after the four of them returned from a bar and went inside Mackey’s house, Thomas went outside for a few minutes. Upon returning, Thomas said that he had shot Starlin. Thomas’s mother testified that when Thomas came to her house on the afternoon of April 18, 2010, he confessed to her that he had shot Starlin. Thomas’s sister, Dezarae Thomas, and her boyfriend, Roger Saul, testified that Thomas had retrieved the gun from Dezarae Thomas’s house around nine or ten o’clock the evening of April 17th. There was conflicting testimony about Thomas’s actions after the shooting and statements he allegedly made earlier in the evening. Dezarae Thomas also testified that when she spoke to her brother on the phone the day after his arrest he said that he was not sorry he had killed' Starlin. Following the close of the government’s case the district court denied Thomas’s motion for judgment of acquittal.
Thomas objected twice during trial on grounds of prosecutorial misconduct, first when the prosecution asked a witness if she had been threatened for testifying at the trial. The district court sustained the objection, gave the jury a curative instruction, and denied Thomas’s motion for mistrial. Additionally, the district court overruled Thomas’s objection to the prosecution’s statement during closing argument that “if this isn’t a first degree murder case, ladies and gentlemen, I don’t know what is.”
II.
We turn first to Thomas’s claim that his statements at his mother’s home and his subsequent confessions should have been suppressed because they were obtained in violation of his Fifth Amendment rights.
“We review
de novo
the legal conclusions underlying the denial of a motion to suppress on Fifth Amendment grounds, while the factual findings are reviewed for clear error.”
United States v. Wise,
*222
Miranda
warnings “protect the individual against the coercive nature of custodial interrogation” and are required only when a person is in custody.
J.D.B. v. North Carolina,
— U.S. -,
We conclude that Thomas’s statements made in his mother’s home were made in a non-custodial setting. Thomas requested that law enforcement come speak to him and invited them inside when they arrived. Although Thomas was not informed that the questioning was voluntary, he was free to move about within his mother’s home, and the officers used no coercive tactics. The police did not deceive Thomas through their questioning, they did not touch him or move toward him in an intimidating manner, and their questioning took place in the presence of Thomas’s mother.
See Griffin,
That Thomas was arrested at the conclusion of Grunder’s short series of questions is a factor that bears consideration. In light of all of the surrounding circumstances, however, especially Thomas’s request that law enforcement come speak to him, we conclude that he was not in custody. Grunder testified that he did not believe he had probable cause to arrest Thomas prior to Thomas’s statement that “he didn’t mean to gun her down.” The district court credited this testimony, and we recognize that the district court has a “distinct advantage” in evaluating credibility, and that its determinations are “virtually unreviewable on appeal.”
United States v. Vinton,
Thomas contends that his confessions made in custody must also be suppressed as “fruit of the poisonous tree” of his first interrogation. This argument necessarily fails because we have determined that there was no initial constitutional violation. Further, “a suspect who has once responded to unwarned yet un
*223
coercive questioning is not thereby disabled from waiving his rights and confessing after he has been given the requisite
Miranda
warnings.”
Oregon v. Elstad,
Likewise, Grander did not employ an impermissible two-part interrogation technique. In
Missouri v. Seibert,
Finally, we note that any error in admitting the statements made in the house would have been harmless. “The admission of statements obtained in violation of
Miranda
may constitute harmless error where there remains overwhelming independent evidence as to the defendant’s guilt.”
Chavez v. Weber,
III.
We consider next Thomas’s contention that his motion for judgment of acquittal should have been granted for want of sufficient evidence.
We review
de novo
the denial of a motion for judgment of acquittal.
United States v. Woman,
The jury’s verdict that Thomas’s action was premeditated and thus constituted first-degree murder is amply supported by the evidence. The district court properly instructed the jury that a killing is premeditated when it results from planning or deliberation, that the time needed for premeditation varies with the circumstances, and that the killer must be conscious of his intent to kill.
United States v. Haskell,
IV.
Thomas’s final contention is that the district court erred in denying his motion for mistrial based on prosecutorial misconduct.
We review for abuse of discretion the denial of a motion for a mistrial based on prosecutorial misconduct.
United States v. Swift,
The district court did not abuse its discretion in denying Thomas’s motion for a mistrial based on a single question the prosecution asked government witness Davida Henry on redirect examination. As recounted earlier, the district court sustained Thomas’s objection to the question whether Henry had been threatened before she testified. After a discussion outside the presence of the jury, the court instructed the jury that “the Court made an inquiry, and you should be aware that there is no evidence that the defendant in this case made any threat against the witness, Davida Henry, directly or indirectly.” Trial Tr. 341. An improper question does not necessitate a mistrial when the objection is promptly sustained and curative instructions are given.
See United States v. Lockett,
Thomas also contends that the prosecutor’s final remark during closing argument was improper. The district court is “vested with broad discretion in controlling closing arguments and we will reverse only on a showing of abuse of discretion.”
United States v. Miller,
The judgment of conviction is affirmed.
