Mark Lamb Biography: Age, Pinal County Sheriff, Height, Wife, Career, Net Worth, Senate Run, Children & Facts

Mark Lamb is an American law enforcement officer, author, and conservative political figure who served as the 24th Sheriff of Pinal County, Arizona, before parlaying his national media profile into a high-profile Republican bid for the U.S. Senate. Known to millions through A&E’s 60 Days In and his own American Sheriff Network, Lamb built a brand around constitutional conservatism, border security, and unapologetic support for Donald Trump. After eight years in office and a bruising 2024 primary loss to Kari Lake, he stepped down from the sheriff’s post at the end of 2024 and entered the private sector, leaving behind a legacy of aggressive policing, political ambition, and persistent questions about financial transparency.

Quick Facts

Early Life & Education

Mark Lamb was born on July 14, 1972, and spent much of his childhood moving internationally, including stints in Hawaii, the Philippines, Panama, and Argentina, where he served his Mormon mission . His peripatetic upbringing exposed him to diverse cultures and, by his own account, made him a minority during his time in Hawaii .

Lamb did not initially plan for a career in law enforcement. In the early 2000s, he was living in Payson, Utah, where he owned a paintball business called Paintball Junkeez . When online shopping and the arrival of a nearby Walmart devastated his sales, the business failed, and Lamb filed for bankruptcy in 2003 . He later wrote about the experience in his self-published 2020 memoir, calling it a humbling lesson in financial resilience.

His pivot to policing came after a ride-along with a neighbor in law enforcement. According to his book, Lamb helped locate a suspect hiding in a trailer that morning and returned home to tell his wife, “I’m gonna be a cop” . He enrolled in the Maricopa County Sheriff’s Office Deputy Academy, where he graduated as Valedictorian of his class .

Career Journey

Early Law Enforcement (2000s–2016)

Lamb began his policing career with the Salt River Pima-Maricopa Indian Community Police Department, where he was named Rookie of the Year and later Officer of the Year . He was promoted to detective in the Gang Enforcement Unit and, in his first year, earned Detective of the Year honors. He also received the Award of Excellence from the Arizona Gang Investigators Association for his work on a multi-agency federal RICO case that dismantled one of the East Valley’s most violent gangs .

He later joined the Pinal County Sheriff’s Office as a deputy to serve the community where he had settled.

Sheriff of Pinal County (2017–2024)

Lamb was elected the 24th Sheriff of Pinal County on January 1, 2017, and took office with a mandate to tighten border security and reduce crime in a county the size of Connecticut . He oversaw a department of more than 650 employees and a budget of approximately $39 million, which included the Pinal County Detention Center housing roughly 600 inmates daily .

He ran unopposed for reelection in 2020 after successfully suing to remove his competition from the ballot, and won with 97% of the vote . During his tenure, the department participated in the federal 287(g) program, allowing detention officers to identify undocumented immigrants for ICE custody .

Media and National Profile

Lamb’s national breakthrough came as the featured sheriff in Season 5 of A&E’s 60 Days In (2019), which sent undercover volunteers into the Pinal County Jail to expose internal flaws . The exposure turned him into a conservative media regular, with frequent appearances on Fox News and Newsmax .

In May 2021, he launched the American Sheriff Network, a subscription streaming service showcasing sheriffs and deputies in action . He also co-founded Protect America Now, a coalition of approximately 69 sheriffs dedicated to constitutional law enforcement .

U.S. Senate Campaign (2024)

In April 2023, Lamb announced his candidacy for the U.S. Senate in Arizona, seeking to replace retiring independent Senator Kyrsten Sinema . Running on a platform of “God, family, and freedom,” he emphasized his border-security credentials and constitutional conservative values .

Despite raising far less money than his opponent and lacking major GOP endorsements, Lamb proved a durable challenger. However, he was defeated in the July 2024 Republican primary by former news anchor Kari Lake, who won by roughly 14 percentage points (409,339 votes to Lamb’s 292,888) . Lake praised Lamb as a “man of great character” during her victory speech, and Lamb later endorsed her in the general election .

Post-Sheriff Career (2025–Present)

Lamb stepped down as sheriff on December 31, 2024, and was succeeded by Ross Teeple . By late 2024, he indicated he was considering a return to the private business sector . He has also expressed interest in potential federal appointments, though he stated in December 2024 that he was not being considered to lead the U.S. Marshals Service or the DEA .

Career Stats & Milestones

Personal Life

Marriage and Family

Mark Lamb married Janel DeRusha on September 23, 1994, after meeting her while both were living in Arizona . Janel, a Minnesota native, is a cosmetologist, former flight attendant, and author of The Sheriff’s Wife . She has been a visible partner in his public life, frequently appearing alongside him at campaign events and media appearances .

The couple has five children: Cade, Sadie, Cooper, Wyatt, and Dayton . In a devastating tragedy, Lamb’s son Cooper, Cooper’s wife, and their infant granddaughter were killed in a traffic collision in Gilbert, Arizona, on December 16, 2022 . The loss deeply affected the family and became a focal point of Lamb’s personal narrative during his Senate campaign.

Faith and Values

Lamb is an active and “unabashed” member of the Church of Jesus Christ of Latter-day Saints . His faith informs his conservative worldview and his emphasis on traditional family values, which became central themes in his book and campaign messaging.

Controversies

Lamb’s career has been marked by several significant controversies, particularly regarding politics, finances, and oversight.

Constitutional Sheriffs and Election Denial

Lamb has been a prominent figure in the Constitutional Sheriffs and Peace Officers Association (CSPOA), a group that promotes the fringe theory that county sheriffs hold supreme legal authority within their jurisdictions . He has described sheriffs as protectors against “government overreach” .

He is a supporter of the Stop the Steal movement and, following the January 6, 2021 Capitol attack, spoke at a rally where he blamed the unrest on “the Hillary Clintons that have gone unpunished” and described the participants as “very loving, Christian people” . In 2022, he partnered with True the Vote to promote ballot drop-box surveillance and an election-fraud hotline, stating, “We will not let happen what happened in 2020” .

Nonprofit and Financial Missteps

In December 2024, investigative reporting revealed that Lamb’s American Sheriff Foundation had lost both its federal tax-exempt status (revoked by the IRS in 2021 for failing to file Form 990s) and its Arizona state nonprofit standing for missing three consecutive annual reports . Lamb had also signed a state disclosure form under penalty of perjury that falsely claimed he had never filed for bankruptcy—a claim contradicted by his own book . He blamed attorneys and staff for the errors, saying, “I guess I should have looked at it a little closer” .

In 2023, it was reported that Lamb’s office had diverted at least $217,000 from a jail commissary fund legally earmarked for “inmate welfare” to purchase weapons, ammunition, and ballistic vests . The Pinal County Board of Supervisors unanimously supported the expenditure after Lamb argued it improved officer safety.

Public Records Lawsuit

In May 2024, the watchdog group American Oversight sued Lamb and Pinal County for failing to respond to five public records requests related to his communications with election-denial activists, anti-immigrant groups, and constitutional sheriffs organizations . The lawsuit settled in late 2024 after the sheriff’s office admitted it had failed to properly comply with Arizona public records law and revealed that text messages from two prior county-issued phones “cannot be retrieved” .

Inmate Welfare Fund Controversy

As noted above, Lamb’s use of inmate commissary funds for law enforcement equipment rather than prisoner welfare drew criticism from government transparency advocates, though local officials defended the decision .

Yet his tenure was shadowed by financial controversies, questions about nonprofit transparency, and his alignment with election denialism. Now out of elected office and exploring private-sector opportunities, Lamb remains a compelling, polarizing figure in the landscape of American law enforcement and right-wing politics.
