Albert Lynn Callahan, 20, of San Antonio was killed on January 28, 2017, in the parking lot of the Days Inn at 13800 Interstate 37 during a drug transaction that went wrong. Callahan had arranged the meeting online and was meeting Michael Paul Reyes and Phillip Anthony Munoz to buy two ounces of marijuana. When Callahan approached the car, he handed the occupants an empty box and struck Reyes; Reyes, who was in the driver’s seat of a Chrysler 300, then shot Callahan. Callahan was later pronounced dead at the scene.

Both Reyes, 21, and Munoz were arrested and charged with murder. Munoz was placed at the scene using cellphone records and later identified Reyes as the shooter in an interview. Reyes was held in the Bexar County Jail on $100,000 bond. The men had communicated with Callahan via Facebook Messenger to arrange the deal.

What details about the meeting or the participants might help explain how this sale turned fatal, and can anyone who knew Callahan or the suspects add information about the events that night?
