According to 1866 City Directory, he was then the city marshal and the sheriff, earning $2000 per annum, while J. N. Lord was deputy sheriff. Duties of marshal also given in 1866 directory, both on this page and scattered throughout other ordinances. He had regularly served as an alderman before and during the war (1858, 1859, 1861-1862), and was city marshall from 1863-1865. He is also listed as marshal in the 1867-1868 city directory.
According to rothkennedy2012, p. 22, he “served in every capacity of Houston city government and was the only Harris County sheriff to be elected mayor of Houston. After serving several terms as alderman he was elected city marshal in 1863, a position he held until he was appointed interim sheriff in 1866 after the current one, John Proudfoot, mysteriously disappeared, most probably as a result of foul play. Lord returned to city marshal in 1867, but was removed by military authorities. … In 1874 he returned as commissioner and the following year was elected mayor.” In 1866, he was sent to New Orleans to study police force there.
