SIERRA MUSSMAN, individually ) and as Personal Representative for ) the Estate of Treyton Mussman, ) ) Plaintiff, ) v. ) Case No. CIV-26-67-R ) FRONK OIL CO., INC. & ) CORY HAMMONDS, ) ) Defendants. )

ORDER Before the Court is the Motion to Dismiss filed by Defendants Fronk Oil Co., Inc. and Cory Hammonds [Doc. No. 15]. Plaintiff Sierra Mussman filed a Response [Doc. No. 19] and Defendants filed a Reply [Doc. No. 21]. The matter is now at issue. BACKGROUND1 The facts as alleged are as follows: On February 14, 2025, Defendant Hammonds was driving a tractor with a tanker propane trailer (collectively, the “semi”) eastbound on County Road Y in Guymon, Oklahoma [Compl., Doc. No. 1, ¶ 7]. At the same time, decedent Treyton Mussman was driving a truck northbound on County Road Mile 30. Id. ¶ 9. Defendant Hammonds and Mr. Mussman approached the intersection between Road Y and Road 30 at the same time. Id. Plaintiff asserts that Defendant Hammonds owed Mr.

1 When reviewing a motion to dismiss brought under Rule 12(b)(6) of the Federal Rules of Civil Procedure, the Court “take[s] the facts in the complaint as true . . . and [ ] views such facts in the light most favorable to the plaintiff[.]” Knellinger v. Young, 134 F.4th 1034, 1042 (10th Cir. 2025) (internal citations and quotation marks omitted). Mussman the right-of-way pursuant to OKLA. STAT. tit. 47, § 11-401(B): “When two vehicles enter or approach an intersection from different highways at approximately the

same time, . . . the driver of the vehicle on the left shall yield the right-of-way to the vehicle on the right.” Id. ¶¶ 13, 30(a). According to Plaintiff, Defendant Hammonds was negligently operating the semi by, among other conduct, speeding and failing to be attentive. Id. ¶¶ 14, 29. Hammonds failed to yield, causing a collision with Mr. Mussman’s vehicle in the intersection. Id. ¶ 29(c). As a result, Mr. Mussman died. Id. ¶ 34. At the time of the accident, Defendant Hammonds was operating the semi as an

agent, servant, and employee of Defendant Fronk Oil, the owner of the semi. Id. ¶¶ 16, 23. Fronk Oil owns and operates 74 total power units and employs 59 drivers. Id. ¶ 20. According to Plaintiff, the semi was endorsed to carry hazardous materials, and Defendant Hammonds required a certification to drive those materials. Id. ¶ 8. Plaintiff brought this action on behalf of herself and as representative for the Estate

of Treyton Mussman, asserting claims for negligence and negligence per se against both Defendants. Defendants have moved to dismiss the Complaint for lack of personal jurisdiction pursuant to Federal Rule of Civil Procedure 12(b)(2), improper venue pursuant to Rule 12(b)(3), and failure to state a claim pursuant to Rule 12(b)(6). In the alternative, Defendants have moved to transfer venue to the Northern District of Texas.

DISCUSSION I. Personal Jurisdiction Defendants first assert personal jurisdiction is lacking because they are not Oklahoma residents and do not have minimum contacts with the state. “Personal jurisdiction over nonresident defendants is proper if an applicable statute authorizes service of process and if the exercise of jurisdiction comports with constitutional due

process.” Hood v. Am. Auto Care, LLC, 21 F.4th 1216, 1220 (10th Cir. 2021). The Federal Rules of Civil Procedure incorporate Oklahoma’s long-arm statute, which is coextensive with the limits of the Due Process Clause. Id.; Dental Dynamics, LLC v. Jolly Dental Grp., LLC, 946 F.3d 1223, 1228-29 (10th Cir. 2020) (citing OKLA. STAT. tit. 12, § 2004(F)). “The Fourteenth Amendment’s Due Process Clause limits the jurisdiction of a state court over a nonresident defendant by requiring that it have ‘certain minimum contacts’

with the forum State to assure ‘that the maintenance of the suit does not offend traditional notions of fair play and substantial justice.’” Hood, 21 F.4th at 1221 (quoting Int’l Shoe Co. v. Washington, 326 U.S. 310, 316 (1945)). Under the specific-jurisdiction requirement, Plaintiff satisfies the minimum-contacts standard by showing that (1) the defendant has “purposefully availed itself of the privilege of conducting activities or consummating a

transaction in the forum state,” Dudnikov v. Chalk & Vermilion Fine Arts, Inc., 514 F.3d 1063, 1071 (10th Cir. 2008) (emphasis omitted) (internal quotation marks omitted); and (2) “‘the litigation results from alleged injuries that arise out of or relate to those activities,’” TH Agric. & Nutrition v. Ace Eur. Grp. Ltd., 488 F.3d 1282, 1287 (10th Cir. 2007) (quoting Burger King Corp. v. Rudzewicz, 471 U.S. 462, 472 (1985)). Plaintiff bears

the burden of establishing personal jurisdiction by only a prima facie showing. Eighteen Seventy, LP v. Jayson, 32 F.4th 956, 964-65 (10th Cir. 2022). “Purposeful availment requires actions by the Defendant which create a substantial connection with the forum state.” OMI Holdings, Inc. v. Royal Ins. Co. of Can., 149 F.3d 1086, 1092 (10th Cir. 1998) (quotation omitted). This “ensures that a defendant will not be subject to the laws of a jurisdiction solely as a result of random, fortuitous, or attenuated

contacts, or of the unilateral activity of another party or a third person.” AST Sports Sci., Inc. v. CLF Distrib. Ltd., 514 F.3d 1054, 1058 (10th Cir. 2008) (quotation omitted). Plaintiff must show the defendant “deliberately ‘reached out beyond’ its home—by, for example, ‘exploi[ting] a market’ in the forum State.” Ford Motor Co. v. Mont. Eighth Jud. Dist. Ct., 592 U.S. 351, 359 (2021) (quotation omitted). Plaintiff presents images of Fronk Oil’s website indicating Fronk supplies western Oklahoma with lubricants and

maintains a facility in Guymon, Oklahoma [Doc. Nos. 19-1, 19-2]. She also asserts Fronk directed Hammonds to drive Fronk’s commercial vehicle into Oklahoma as part of substantial, ongoing operations there, and the collision occurred while Hammonds was engaged in those operations near Guymon.2 These assertions amount to a prima facie showing that Fronk Oil deliberately exploited Oklahoma markets such that it has sufficient

minimum contacts with Oklahoma.3

2 “The plaintiff may make [a] prima facie showing [of personal jurisdiction] by demonstrating, via affidavit or other written materials, facts that if true would support jurisdiction over the defendant.” OMI Holdings, 149 F.3d at 1091. The Court will consider the documents Plaintiff attached to her Response solely to determine whether she has made a prima facie showing. See 24-7 Mach., LLC v. Warren Power & Mach., Inc., No. CIV-23- 159-PRW, 2024 WL 1183071, at *3 n.16 (W.D. Okla. Mar. 19, 2024). 3 Indeed, considering the documents attached to Plaintiff’s Response, the Court marvels at Defendants’ representations that the collision was an “isolated incident, not part of any pattern of conduct directed at Oklahoma . . . .” and that Defendants “did not seek out” Guymon “as a forum for their activities, nor . . .
