GRAVOIS, J.

Relator, the State of Louisiana, seeks this Court’s supervisory review of the

trial court’s ruling which granted an application for a bill of particulars filed by

defendant, Isaiah Bernard a/k/a Isaiah Mayes. For the following reasons, we deny

the writ application.

FACTS AND PROCEDURAL BACKGROUND

On January 30, 2024, the Jefferson Parish District Attorney filed a bill of

information charging defendant with the vehicular homicide of David Smith while

engaged in the operation of a motor vehicle and under the influence of alcohol in

violation of La. R.S. 14:32.1. On September 12, 2025, defendant filed an

application for a bill of particulars, arguing that the State failed to identify in the

bill a causal relationship between the death of Mr. Smith and defendant allegedly

being under the influence of alcohol while engaged in the operation of a motor

vehicle. The State filed a response, asserting that it tendered open file discovery

relieving it of the need to answer a bill of particulars. The State acknowledged that

it will have to prove causation at trial beyond a reasonable doubt, but argued it did

not need to provide a roadmap of how it intends to prove its case.

Following a hearing, on September 25, 2025, the trial court granted the

application for a bill of particulars and ordered the State to provide and identify the

causal relationship between the death and defendant allegedly being under the

influence of alcohol. In written reasons, the trial court stated that causation must

be proven at trial and is therefore an element of the offense that defendant should

be adequately apprised of prior to trial.

ANALYSIS

Article I, § 13 of the Louisiana Constitution requires that an indictment

inform a defendant of the nature and cause of the accusation against him. State v.

Fuxan, 24-302 (La. App. 5 Cir. 5/14/25), 415 So.3d 387, 410. La. C.Cr.P. art. 464

25-K-461 1

provides that the indictment shall be a plain, concise, and definite written statement

of the essential facts constituting the offense charged. The State may provide that

information in the indictment alone or in its responses to a defense request for a

bill of particulars. State v. DeJesus, 94-0261 (La. 9/16/94), 642 So.2d 854, 855.

The time for testing the sufficiency of an indictment or a bill of information

is before trial by way of a motion to quash or an application for a bill of

particulars. State v. Robinson, 22-310 (La. App. 5 Cir. 4/12/23), 361 So.3d 1107,

1118. La. C.Cr.P. art. 484 provides in part that a motion for a bill of particulars

may be filed of right in accordance with Article 521. The court, on its own motion

or on motion of the defendant, may require the district attorney to furnish a bill of

particulars setting forth more specifically the nature and cause of the charge

against the defendant. La. C.Cr.P. art. 484. The purpose of the bill of particulars is

to inform the accused more fully of the nature and scope of the charge against him

so that he will be able to defend himself properly and to avoid any possibility of

ever being charged again with the same criminal conduct. State v. Robinson, 20-

1389 (La. 3/9/21), 312 So.3d 255, 256. The defendant is entitled to know what the

State intends to prove; but the bill of particulars cannot be employed in a fishing

expedition for a recital of the details of the State’s evidence, nor used as a device to

harass the State by demands for nonessential details. La. C.Cr.P. art. 484, official

revision comment (a).

Generally, open file discovery relieves the State of the necessity of

answering a motion for a bill of particulars. However, open file discovery cannot

be used as a substitute for a bill of particulars for purposes of La. C.Cr.P. art. 485.

Louisiana v. T.E., No. 23-K-596, 2024 WL 110242 (La. App. 5 Cir. Jan. 20, 2024),

writ denied, 24-159 (La. 6/19/24), 386 So.3d 673.

The matter of furnishing a bill of particulars rests largely in the discretion of

the trial judge, and his discretion will not be disturbed unless there is error in the

25-K-461 2

ruling complained of to the detriment or disadvantage of the accused. State v.

Gravois, 17-341 (La. App. 5 Cir. 12/13/17), 234 So.3d 1151, 1174, writs denied,

18-100 (La. 3/23/18), 239 So.3d 292, and 18-80 (La. 3/23/18), 239 So.3d 298.

In State v. Miller, 319 So.2d 339 (La. 1975), the Louisiana Supreme Court

set forth some factors to be considered in determining whether a defendant was

given all of the information to which he is constitutionally entitled:

The state is required, upon defendant’s motion, to provide a
criminal defendant with enough information so that he can identify
the criminal transaction. There is no exact formula which can be
applied to every charge to determine in a particular case whether a
defendant has all of the information to which he is constitutionally
entitled. In general, however, the extent to which the bill should
be granted turns on the complexity of the case. If the crime is a
single event, such as a murder, the scope of the bill will be less
extensive than it will be if the crime involved is a series of
occurrences, such as tax fraud or bootlegging. When a crime
charged may be committed in a number of different ways, this
Court has always recognized the accentuated need for the state to
furnish particulars.

Id. at 342-43 (internal citations omitted). The Supreme Court also acknowledged

that in providing information in response to a bill of particulars, the State may be

forced to release facts which reveal what its evidence will prove at trial. The court

said it has never held that the State is free from answering a bill of particulars

because doing so would reveal particular facts which it intends to establish through

evidence. Id. at 343.

In the present case, defendant was charged with vehicular homicide. At the

time of the offense, La. R.S. 14:32.11 provided, in pertinent part:

A. Vehicular homicide is the killing of a human being caused
proximately or caused directly by an offender engaged in the
operation of, or in actual physical control of, any motor vehicle,
… whether or not the offender had the intent to cause death or
great bodily harm, whenever any of the following conditions
exist and such condition was a contributing factor to the killing:

1
La. R.S. 14:32.1 was amended, effective August 1, 2024.

25-K-461 3

(1) The operator is under the influence of alcoholic beverages as
determined by chemical tests administered under the
provisions of R.S. 32:662.

(2) The operator’s blood alcohol concentration is 0.08 percent
or more by weight based upon grams of alcohol per one
hundred cubic centimeters of blood.

(3) The operator is under the influence of any controlled
dangerous substance listed in Schedule I, II, III, IV, or V as
set forth in R.S. 40:964.

(4) The operator is under the influence of alcoholic beverages.

(5) (a) The operator is under the influence of a combination of
alcohol and one or more drugs which are not controlled
dangerous substances and which are legally obtainable
with or without a prescription.
(b) It shall be an affirmative defense to any charge under this
Paragraph pursuant to this Section that the label on the
container of the prescription drug or the manufacturer's
package of the drug does not contain a warning against
combining the medication with alcohol.

(6) The operator is under the influence of one or more drugs
which are not controlled dangerous substances and which
are legally obtainable with or without a prescription and the
influence is caused by the operator knowingly consuming
quantities of the drug or drugs which substantially exceed
the dosage prescribed by the physician or the dosage
recommended by the manufacturer of the drug.
(7) The operator's blood has any detectable amount of any
controlled dangerous substance listed in Schedule I, II, III,
or IV as set forth in R.S. 40:964, or a metabolite of such
controlled dangerous substance, that has not been medically
ordered or prescribed for the individual.

The plain text of the statute requires the State to prove four things: 1) the

killing of a human being; 2) caused proximately or caused directly by an offender

engaged in the operation of, or in actual physical control of, any motor vehicle; 3)

a prohibited degree of intoxication; and 4) a link between the intoxication and the

killing. The link between the intoxication and the killing does not have to be a

“proximate cause,” but simply a “contributing factor.” See State v. Leger, 17-2084

(La. 6/26/19), 284 So.3d 609, 615-16. A “contributing cause” is a factor that—

25-K-461 4

though not the primary cause—plays a part in producing a result. A “factor” is an

agent or cause that contributes to a particular result. Id. at 616.

In the present case, the bill of information alleges that defendant “violated

La. R.S. 14:32.1 in that he did kill one David Smith, while engaged in the

operation of a motor vehicle and under the influence of alcohol.” As established

and agreed upon by all parties, at trial, the State will have to prove the information

defendant now seeks—the causal relationship between the victim’s death and

defendant allegedly being under the influence of alcohol.2 Upon review, we

conclude that the bill of information does not provide this essential fact and the

scant information provided in the bill of information hinders defendant’s ability to

properly defend himself. Additionally, we conclude that the State cannot refuse to

furnish a bill of particulars here just because it may reveal particular facts that it

intends to establish through evidence. See Miller, 319 So.2d at 343. Accordingly,

we conclude that the trial court did not abuse its broad discretion in granting

defendant’s application for a bill of particulars.

DECREE

This writ application is denied.

WRIT DENIED

2
There are several ways that intoxication can cause a death in a vehicular homicide case.
See e.g., State v. Clement, 23-1356 (La. App. 1 Cir. 12/10/24), 404 So.3d 739, 749, writ denied,
25-39 (La. 4/1/25), 404 So.3d 655 (“Based on the numerous substances impacting the
defendant’s state of mind and physical functioning, the jury could have rationally concluded the
defendant’s intoxication impaired his judgment and caused him to excessively speed on a dark,
dangerous highway, contributing to the victims’ immediate deaths on impact.”); State v. Bazar,
55,143 (La. App. 2 Cir. 6/28/23), 367 So.3d 940, 947 (The defendant, who had been drinking,
was speeding and swerved his truck into oncoming traffic colliding head-on with another vehicle
without braking, resulting in the victim’s death.); State v. Melancon, No. 2021 KA 1489, 2022
WL 4286614 (La. App. 1 Cir. Sep. 16, 2022), writ denied, 22-1544 (La. 1/25/23), 354 So.3d 9
(The defendant’s intoxication impaired his ability to see the approaching motorcycle and caused
him to improvidently pull out in front of it, resulting in the victim’s death.); State v. Magrini, 19-
951 (La. App. 4 Cir. 5/27/20), 301 So.3d 525, 539 (The defendant’s impairment dulled his
thought processes, his reflexes, and motor functioning, and affected his decision-making to a
degree sufficient to be a contributing factor of the victim’s death.); State v. Vidrine, 19-906 (La.
App. 4 Cir. 4/15/20), 298 So.3d 781, 799, writ denied, 20-579 (La. 1/12/21), 308 So.3d 293 (The
defendant, in his impaired condition, failed to notice traffic lights and sped through a red light.).
