Alexandria Newberry

Human Resources Director

Swamptown Police Department

843 Pollen St.

Swamptown, FL, 12345

Dear Ms. Newberry,

As the investigator responsible for solving over a dozen cold cases within the past 4 years, I find the prospect of working for the Swamptown Police Department an exciting and fitting opportunity. After all, I’m a highly motivated and dedicated person, who has extensive knowledge of Florida law, as well as experience filing reports, processing crime scenes, interviewing witnesses, and examining evidence.

Within the past 6 months alone, I located the pair of shoes that directly correlated with a shoe track cast taken from the crime scene of an armed robbery case that had gone cold for over a year. After reopening the case, I had the shoes DNA tested, ultimately leading to the arrest of the man who’d been robbing houses all over local towns for two years. With that in mind, I believe my specialization in solving cold cases and giving valuable insight into new cases will make me a sound addition to your department’s already impressive team. Overall, here are a few examples of my accomplishments:

  • Solved over a dozen reopened cases in only 4 years
  • Graduated from Florida State University with a degree in Criminal Justice
  • Worked at the Stamford Police Department as an investigator for 7 years

If you’re looking for a highly experienced, skilled, and dedicated investigator, my accomplishments clearly outline my capabilities. Therefore, I hope you will consider my application, and I look forward to hearing back from you. You can reach me at (777) 777-777, or

Best Regards,

Thomas Jinton”

City County Police Department

Dear Ms. Anderson,

I’m writing to you today to express my interest in applying for the criminal investigator position available with the City County Police Department. I was excited to see the job posting on your website. My desire to work in public service and seek justice for victims drives my passion for work, and I believe this, along with my credentials, could make me a good fit for this position.

Before beginning my career, I attended Sunshine State University, earning a bachelor’s degree in criminal justice with a minor in psychology. During this time, I also completed an internship with the local government focused on processing background checks. This helped me develop problem-solving skills and learn how to deal with confidential information, and I earned special recognition for my service as an outstanding graduate in my class.

I’ve served as a police officer in the Rural County Police Department for 12 years. My experience as a police officer provided me with real-world application of my knowledge of the law, and I honed my observational and interpersonal skills. I’m confident in my critical and analytical thinking, interviewing and communication skills. I often work closely with our crime scene investigation team and detectives to find solutions to their open cases, and I’ve taken part in frequent cross-training programs with them to improve my skills.

Again, I am very excited about the possibility of joining the City County Police Department as an investigator. I appreciate your time today and your consideration of me for this job. I’ve included my resume to further outline my experience, and I’m available to discuss this position at your convenience. I look forward to hearing more from you soon.

David Eastwood

Human Resource Executive,

Browns & Williams Detectives,

9000 Imperial Highway,

Downey, CA 90242

Dear Mr. Eastwood,

This is with reference to your advertisement in the “Los Angeles Times”, dated November 15, 2011, inviting applications for the post of private investigators. I satisfy all the eligibility conditions prescribed by you and I am interested in the said position. I have ten years experience as an investigating officer with the Los Angeles Police Department (LAPD) followed by two years of private detective experience with Smuts & Mitchell Detective Services. I am interested in working with an agency that is the top name in this field and hence the application to your organization.

My experience as a detective has enabled me to be cognizant with all aspects of this job.

I am well aware of all the laws and rules associated with this line of work. I am licensed to carry a small firearm and I am completely comfortable with the application of surveillance devices like high speed motion cameras, tiny microphones, miniature transmitters, recorders etc. I am also familiar with the use of appropriate software for the storage and transmission of such data.

I have maintained a fair level of physical fitness and I am used to working at all times of the day and night. I get along comfortably with people and can make up stories, something that helps me gather information without revealing the true purpose of the enquiry. Regarding education, I have a college degree in arts and a certification in Surveillance and Related Communication; the later I completed during my stint with the LAPD.

I am interested in working for an organization, like yours, that understands the point of view of its employees and that has a sober working culture. Your impressive track record in investigation is another reason for this application. You can get in touch with me on the telephone number or the email address I have mentioned. I am awaiting your reply.

Yours Sincerely,

(Martin Boltzmann)”
