Big Bad Wolf was responsible for the operation 'Mary's Little Lamb' which involved Calvin van Lowe's development of a modified assaultron unit. He was not enthusiastic about the operation and its expected returns, expressing this to van Lowe's handler, code name Bo-Peep, in a letter.
After Bo-Peep missed a scheduled meeting, Wolf investigated and found that she was killed by van Lowe's modified assaultron unit while waiting to meet him in Bastion Park. After reporting this to Bysshe Headquarters, he went to Van Lowe Taxidermy, intending to conduct a "removal", presumably of the company's assaultron unit. While making his check-in, he killed two Lewisburg police officers.
After discovering that the assaultron unit had gone missing, he messaged Bysshe headquarters to request equipment which would aid in its retrieval. Given the urgency of the situation, he was unwilling to wait for back up and set up a capture site in the Ash Heap, planning to attempt a solo capture. Recognizing the inherent riskiness of attempting a solo capture, he left a spare assaultron recall keycard and plans in the trunk of a car on the top floor of the Garrahan Estate. He was presumably killed in the endeavour.
