Mesa Verde Construction is a construction company funded by Jack Travis, an ex-cop who uses his company as a cover up for his illegal activities in the arms dealing business.
The company is most known for being involved in the development of Rancho Arroyo at the time of his crimes, and possibly in the subway station as well, since it is located directly near a police garage. Many of the workers in the company are ex-cons whom Travis, personally has employed with the company. However, some were unaware of his actual intentions as an armor piercing cop killer.
Following the events of Lethal Weapon 3, it is unknown what became of Mesa Verde in the aftermath of the shootout at Rancho Arroyo.
