Malcom Whiting, accompanied by Celina's School Resource Officer Justin Bruns, wants to be a police officer someday. Mercer County Head Start proudly presented its recently published book "From Crayons to Careers," written by students from the Lakeside Learners class, during a book premiere at the Celina auditorium on Wednesday afternoon. The book contains the students' hopes and dreams for the future. During the premiere, 18 students ages 3-5 walked across the stage dressed as what they want to be when they grow up alongside a real-world counterpart.
