Opinion

IN THE SUPREME COURT OF THE STATE OF DELAWARE

JASON WILCOX, § § Defendant Below, § No. 44, 2025 Appellant, § § Court Below: Superior Court v. § of the State of Delaware § STATE OF DELAWARE, § Cr. ID No. 2405010892 (S) § Appellee. § §

Submitted: November 12, 2025 Decided: February 6, 2026

Before SEITZ, Chief Justice; LEGROW and GRIFFITHS, Justices.

ORDER

The Court, having considered the briefs and the record below, rules as follows:

(1) While driving over the speed limit on Delaware Route 9, Jason Wilcox

crashed into a minivan driven by Jason Wright with his six family members. Wilcox

fled the scene. Three people in the minivan were killed and four others injured. A

grand jury indicted Wilcox for crimes related to the collision. A jury found him

guilty of all charges. The Superior Court sentenced Wilcox to lengthy incarceration

followed by decreasing level of probation.

(2) Wilcox has appealed his convictions, claiming that the Superior Court:

(a) erred in denying his motion to compel Brady material, (b) erred by admitting into evidence data from his car’s electronic data recorder (“EDR”), and (c) under plain

error review, erroneously instructed the jury as a matter of law. We affirm.

(3) On December 24, 2022, around 8 p.m., Wilcox was driving his 2016

Range Rover Sport westbound on Lewes-Georgetown Highway (“Route 9”) in a 50

mile an hour speed limit zone. The two-lane road was dry, the weather clear. Cars

on Route 9 have the right-of-way and a clear view of the intersection where the

collision occurred. After stopping at a stop sign at the intersection of

Minos/Conaway Road and Route 9, Wright entered the Route 9 westbound lane

(Wilcox’s lane) in his Honda Odyssey minivan with six family members. He

intended to turn left onto eastbound Route 9. The cars collided. The Range Rover’s

EDR showed that, five seconds before the crash, Wilcox accelerated from 73.50

miles per hour to 82.34 miles per hour. The EDR recorded the Range Rover impact

speed at 81.16 miles per hour.1

(4) Three minivan occupants were killed, and four others seriously injured.

Wilcox fled the scene. A grand jury indicted Wilcox for three counts of

Manslaughter, four counts of Assault First Degree, one count of Speeding, one count

of Leaving the Scene of a Collision Resulting in Death, one count of Failure to

1 App. to Appellant’s Am. Opening Br. at A18-19, A274, A282, A437, A440-42, A614-16, A747- 48, A763-64, A785-86, A810-11 [hereinafter A___].

2 Report a Collision Resulting in Injury or Death, one count of Assault Second Degree,

and one count of Assault Third Degree.2

(5) Prior to trial, Wilcox filed a motion to compel disclosure of grand jury

proceedings related to Wright and the collision. Wilcox speculated that the State had

attempted to indict Wright for collision-related charges because he had some

culpability for the collision. Thus, according to Wilcox, he was entitled to the basis

for the State’s decision to attempt to indict Wright. The court denied the motion,

ruling that grand jury proceedings are confidential, and no exception applied.3

(6) Wilcox followed the denial of his motion to compel with a non-

specific motion to compel Brady4 material. Wilcox argued that “logic would dictate”

that Wright’s driving “likely violated” several motor vehicle laws.5 According to

Wilcox, none of the State’s evidence shared with Wilcox showed that Wright was at

fault. Therefore, he speculated, there must be more evidence that was not shared

with the defense. The court denied the motion, reasoning that the State represented

2 A3, A606-08. 3 A5, A117-125, A131-32, A167-68. 4 Brady v. Maryland, 373 U.S. 83 (1963). 5 A144-45.

3 that it had provided all non-privileged materials related to the collision and was not

required to disclose its theory or possible charges against Wright.6

(7) During trial, Wilcox objected to the admissibility of data from the

Range Rover’s EDR and an RCM Readout Report that analyzed the car’s actions

just before the collision.7 The court excluded the RCM Readout Report as hearsay

but relied on Delaware Rule of Evidence 901(a) to admit into evidence the data from

the EDR.8

(8) The parties attended two prayer conferences which, in part, addressed

a foreseeability jury instruction. Wilcox did not object to the following instruction

addressing the foreseeability of actions by other drivers: “If you find that the

Defendant could not have reasonably anticipated or foreseen or was not aware that

the other driver’s motor vehicle would enter the intersection, you must find that

Defendant’s actions were not reckless [or criminally negligent].”9 After closing

statements, the jury found Wilcox guilty of all charges. He was sentenced to 156

6 A167-68. 7 A156-65, A528-39, A542-54, A662-63. The RCM Readout Report contained information regarding occupant status, acceleration, speed, brake usage, steering wheel usage, safety device deployment. A156-65. 8 A658-63. 9 A1017-18, A1161-62.

4 years at Level V suspended after 17 years and 6 months for decreasing levels of

supervision.10

(9) As noted earlier, Wilcox raises three errors on appeal. First, he contends

that the State did not disclose all exculpatory material in its possession related to the

State’s alleged failed attempt to indict Wright for offenses related to the collision.

According to Wilcox, the information would be exculpatory to rebut the inference

that Wilcox was the sole cause of the crash. Second, Wilcox argues that the court

erred by admitting data from the Range Rover’s RCM Readout Report because it

was not self-authenticating, and chain of custody was not proven. And finally, in a

new argument on appeal, Wilcox claims that the court’s foreseeability jury

instruction was erroneous as matter of law because it implied that Wilcox had a duty

to anticipate the negligent acts of other drivers.

(10) We review questions of law de novo, including whether the State failed

to disclose exculpatory or impeachment evidence.11 We review a court’s decision to

admit evidence to determine whether the court exceeded its discretion.12 We review

10 A10; Exhibit A to Am. Opening Br. 11 Mobley v. State, 346 A.3d 1127, 2024 WL 5316320, at *6 (Del. Dec. 5, 2024) (TABLE); McGuiness v. State, 312 A.3d 1156, 1179 (Del. 2024). 12 Burrell v. Delaware, 332 A.3d 412, 424 (Del. 2024).

5 a court’s decision to issue challenged jury instructions de novo.13 This Court will

review forfeited arguments for plain error.14

(11) Under Brady v. Maryland, prosecutors must disclose exculpatory

evidence in their possession that might be material to the outcome of the case.15 To

establish a Brady violation, a defendant must prove: “(1) evidence exists that is

favorable to the accused, because it is either exculpatory or impeaching; (2) that

evidence is suppressed by the State; and (3) its suppression prejudices the

defendant.”16

(12) Wilcox contends that he learned before trial that the State attempted to

indict Wright for collision-related charges but failed to secure an indictment.

According to Wilcox, there must have been more undisclosed evidence regarding

Wright’s fault. Wilcox says that the State’s failure to disclose the unidentified

exculpatory material violated Brady.

(13) Wilcox, however, stumbles on his assumption – that the State has Brady
