Los Angeles Board of Public Works President Andrea Alarcon announced Friday that she is resigning from her post, and she apologized for what she described as "the missteps of my past."

Police have been investigating Alarcon, 33, on suspicion of child endangerment after her 11-year-old daughter was found unattended at City Hall on the night of Nov. 16. She also is facing separate child-endangerment and drunk-driving charges in San Bernardino County.

Alarcon, an appointee of Mayor Antonio Villaraigosa, did not mention either incident specifically in her announcement, saying instead that she had learned "difficult lessons."

"I understand and have prayed deeply on the gravity of my actions. I have profound regret for the missteps of my past and apologize to the Mayor, Council, Department of Public Works, the city family and the residents of Los Angeles," she said in a statement.
