James Richard Dunlop, 29, was killed on September 10, 2017, in a mass shooting at a home on West Spring Creek Parkway in Plano, Texas. The gathering was a Dallas Cowboys watching party hosted by Meredith Lane. Dunlop had been the best man at Lane’s wedding to Spencer James Hight, who carried out the attack.

Hight, described as Lane’s estranged husband, allegedly had a history of physical abuse and had lost his contracting job; he reportedly struggled with alcoholism and had been the subject of a divorce filing earlier that year. Hight killed eight people and injured one before being shot and killed by police. Plano police and the Texas Rangers investigated the scene, and no further arrests followed.

Dunlop was remembered by family and friends as a bright, accomplished man who graduated with honors from Allen High School and earned a Master’s Degree in R.F. Engineering from the University of Texas Dallas. Does anyone who knew James or attended that gathering have details to share with investigators or the community?
