Following his departure from the service, he joined the New Mexico State Police (NMSP). He proudly served for 22.5 years, ending his career as a sergeant stationed in Truth or Consequences, New Mexico in September, 1985. However, his days of service were far from over.

Once the term was over, he came back home to T or C. Then he worked for a year as Sierra County Jail Administrator. And lastly, he finished his public service serving two terms as Sierra County Commissioner for eight years. He retired from public life to enjoy hobbies of fishing, camping, rock hunting, attending Hot Springs Tiger Football games, wood working (which included the router and whittling) and he owned and loved his classic Harley Davidson motorcycle. He was affectionately known by the Elephant Butte NM VFW Post 44 Motorcycle group as Snoopy. A poker run was one of his favorite things to do with the group. He was a member of 3 Masonic lodges located in T or C, Hillsboro and Mimbres. He served in various offices and was master in both the T or C and Hillsboro lodges. He was also a Rotarian for many years and continued his association with NMSP as an alumni/retirees. He was preceded in death by his parents; his brother, Jerry Coslin; and a grandson, Bryden Bruton.
