Types of Criminal Cases We Handle

McCarthy and Hamrock, P.C. defends clients charged with a wide array of offenses in Story County District Court and Juvenile Court. Some of the most common cases we take on include:

Domestic Abuse and Protective Order Violations – Domestic violence accusations often arise after emotionally charged situations between family or household members. These cases can result in immediate arrests, no-contact orders, and firearm restrictions. We help clients challenge false claims and fight to restore their rights.

Drug Offenses – Story County law enforcement and campus police closely monitor drug activity in Ames and surrounding areas. Charges may involve marijuana, LSD, psilocybin, Adderall, or fentanyl. Our team investigates for illegal search and seizure, coerced confessions, or unreliable lab results to defend your case.

White Collar and Fraud Crimes – Whether it’s theft from a workplace, online identity fraud, or misuse of financial accounts, these offenses are often complex and document-heavy. We have experience managing cases involving embezzlement, elder fraud, unemployment benefit abuse, and student loan fraud.

Weapons Charges – From unauthorized possession to use of a weapon during another crime, firearms cases in Iowa carry serious penalties. If you’re a student, immigrant, or have a prior record, your legal rights may be impacted even more. We defend against unlawful searches, mistaken identity, and procedural violations.

Probation Violations – Violating the terms of your probation, even unintentionally, can lead to jail time. We represent clients accused of missed check-ins, failed drug tests, or new charges while on probation and work to keep them out of custody.

Sex Offenses – Charges such as sexual assault, child exploitation, or online solicitation are among the most serious in Iowa law. We offer discreet and thorough defense, often challenging the credibility of accusers or the sufficiency of digital evidence. Early legal intervention is essential in these cases.

Violent Crimes – Story County prosecutors are aggressive in pursuing felony assault, robbery, attempted murder, and related charges. Self-defense, lack of intent, or inconsistent witness testimony may be key elements of your defense.

Property Crimes and Theft – Shoplifting, burglary, vehicle theft, and criminal mischief cases often hinge on surveillance evidence and police interviews. First-time offenders may qualify for diversion or deferred judgment. We work to protect your record and negotiate favorable outcomes.

Traffic Charges – Our attorneys also defend hit-and-run, driving while barred, and eluding law enforcement.

Juvenile Offenses – Youthful mistakes can have long-lasting consequences if not handled with care. We represent minors facing charges for theft, drug use, underage drinking, and school-related incidents, helping them avoid a permanent criminal record and focusing on rehabilitation over punishment.

Story County OWI Defense

With Iowa Highway 30, U.S. Highway 69, and Interstate 35 running through Story County, OWI enforcement is a priority for local and state law enforcement agencies. Patrol units and campus police in Ames frequently conduct OWI stops near campus housing, downtown bars, and major roadways.

A conviction for Operating While Intoxicated (OWI) in Iowa can result in license revocation, steep fines, and even jail time, especially if you have prior offenses. Field sobriety tests and breathalyzers are not always administered correctly, and we examine every step of the arrest process to challenge weak or unlawful evidence.

Our attorneys understand the impact an OWI conviction can have on students, professionals, and anyone who relies on their driving privileges. We explore alternatives such as deferred judgment, substance abuse treatment, or dismissal when possible.
