Houston police say catalytic converter thefts have increased this year, with the number of reported cases already surpassing annual totals recorded in each of the past two years.
Court documents allege the 67-year-old stole nearly $70,000 from 14 people after telling them he could fix their bad credit to help them get a car.
Police say the suspect is a repeat car burglar with more than 20 prior charges who was out on bond when the Navy recruit was killed.
Officers said they found guns, removed transmissions, catalytic converters, and $17,000 in cash during a warrant execution in an auto-theft case.
"I trust(ed) a police officer," said a man who was tricked into buying a stolen Lexus from a former Harris County detention officer and a former inmate, court documents allege.
Houston police say thieves are targeting commercial vans not for the vehicle, but for the tools and equipment inside.
