LAS CRUCES, N.M. -

Authorities in Las Cruces say someone stole a gun and a Taser out of a Dona Ana County Sheriff's car at the Mesilla Valley Mall.

According to investigators, an off-duty sheriff's sergeant had his marked vehicle parked at the mall when someone broke the front window before taking off with a gun, ammunition, a Taser, and handcuffs.

When questioned why the sergeant took all his equipment to the mall, investigators say he was just obeying the rules.

"Yes, he was off-duty; however, he was on-duty so far as being on call which required him to have his uniforms, his equipment, and his vehicle there, ready to be able to respond," said Bo Nevarez of the Dona Ana County Sheriff's Office.

The burglary happened earlier in July; the equipment was valued at about $4,000.
