Background

In August 2022, Derrick choked, punched, and assaulted his girlfriend (Victim 1) in their home. Police responded, documented injuries, and Victim 1 obtained an order of protection. Following the assault, Derrick sent Victim 1 numerous threatening text messages over several days, including threats to shoot her in the head, kill her with an AK-47, and statements like “Either we gonna be together or I’m killing us both” and “If you don’t want to deal with me, you going to be dealing with violence.”

Approximately 2.5 months later, on November 5, 2022, Victim 1 called her grandmother (Victim 2) requesting help to leave Derrick’s home. As Victim 2 arrived to help, Victim 1 called 911 to report that Derrick was armed, abusive, and threatening to kill her and her mother. During the 911 call, Derrick shot both women multiple times within nine seconds. Victim 1 was shot twice—in the left armpit and right back—and died from injuries to her lung, heart, and liver. Victim 2 was shot twice and died from injuries to her liver, stomach, and small intestine.

Derrick’s account at trial differed substantially from the 911 call and physical evidence. He claimed Victim 1 had the gun and fired at him, hitting her mother instead, and that he shot her in self-defense. A detective testified that Derrick’s timeline was inconsistent with the nine-second window between gunshots, that the ballistics contradicted his account, and that his physical size advantage over the 4’10”, 117-pound Victim 1 undermined the struggle narrative.

The Court’s Holding

The court held that joinder of the August 2022 domestic assault charges with the November 2022 homicide charges was proper. Although separated by two months and involving a different victim in one count (Victim 2), the offenses were connected and part of a common scheme. All charges involved domestic violence acts against Victim 1 across a 12-week span at the same location. The threatening text messages between the incidents and Derrick’s fatal shooting of both victims while threatening Victim 1 demonstrated a continuing pattern to control her and prevent her from leaving the relationship.

The court further held that denial of Derrick’s motion to sever was not an abuse of discretion. Derrick failed to make a particularized showing of substantial prejudice. The evidence regarding each offense was sufficiently simple and distinct—the August incident had separate video and photographic evidence, while the November incident involved the 911 call and police body camera footage. The jury received instructions to consider each count separately and demonstrated its ability to distinguish evidence by acquitting Derrick of the endangering-the-welfare-of-a-child charge while convicting him on other counts.

The court rejected Derrick’s argument that combining the “strangling” allegation with the shooting incidents had an inflammatory effect, finding this conclusory without specific factual support. Additionally, evidence of the prior August assault would have been admissible at a separate murder trial to show motive and intent, particularly where Derrick raised a self-defense claim, so no additional prejudice resulted from joinder.

Key Takeaways

  • Joinder of offenses separated by two months is proper when they involve the same victim, the same location, and constitute parts of a common scheme of domestic violence and control.
  • Severance requires a particularized showing of substantial prejudice; conclusory allegations that evidence of one charge will prejudice another are insufficient.
  • Prior bad acts in domestic violence cases are admissible to show motive and intent, particularly when self-defense is claimed, making separate trials unlikely to change admissibility.
  • A jury’s ability to distinguish charges and apply law separately is demonstrated by acquittals on some counts while convicting on others, even when charges are joined.

Why It Matters

This decision reinforces that courts view domestic violence as recurring conduct forming a continuous pattern. The court’s acceptance of joinder across a two-month gap signals that prosecutors need not charge domestic violence incidents separately even when they occur at different times, provided they involve the same victim and location. This may simplify case administration but could also expose defendants to cumulative prejudice from evidence spanning extended periods of alleged abuse.

The ruling also solidifies that prior domestic violence acts are highly probative in later assault or homicide cases, particularly when self-defense is the defense. This underscores the importance of the temporal and circumstantial connection between incidents—the threat pattern and escalation narrative become central to proving intent and motive rather than accident or justified self-defense.
