King County Sheriff's Office press release:

The City of SeaTac announced on April 17 that King County Sheriff’s Major Lisa Mulligan has been selected as the City’s new Police Chief. Mulligan will replace Chief James Graddon who is retiring this month after serving as SeaTac’s Police Chief for over 6 years.

Major Mulligan is a 28 year veteran of the King County Sheriff’s Office. Most recently she served as the contract Chief of Metro Transit Police. She has also served as Assistant Commander of the Washington State Criminal Justice Training Center and spent much of her career patrolling the southwest area of King County as a deputy and sergeant.

SeaTac City Manager Todd Cutts said, “I believe she will be a great addition to our team here in SeaTac.” Cutts also said a formalized start date has not been set yet, but he expects she will start in late April or early May.

The City of SeaTac has contracted with the King County Sheriff’s Office for police services since incorporating in 1990. “Major Mulligan is a great choice for the City of SeaTac,” said King County Sheriff John Urquhart. “She is well respected and a great leader.”
