A Dallas man has been arrested after allegedly hitting and killing a pedestrian while drunk driving, and then driving to his place of employment with he victim’s severed arm in the passenger seat of the vehicle.

The Dallas Police Department confirmed to PEOPLE that Juan Morgan Munoz, 31, was arrested and charged with felony DWI and collision involving death. They added that additional charges are possible.

He was taken to the Dallas County jail after reportedly fleeing the scene of the fatal accident, according to news outlets KDFW and WFAA.

The driver reportedly confessed to hitting the victim near Storey Lane and I-35E, but continued on his way to work about a mile away, according to both news outlets.

Authorities arrived at Munoz's job at Maaco Auto Body Shop after Munoz made his phone call, according to the outlets. They allegedly found his white BMW with a "hole in the front passenger windshield" and "an entire arm on the front passenger seat" along with blood.

He also reportedly had "glassy/watery eyes, slurred speech and a strong odor of an alcoholic beverage,” according to an arrest warrant affidavit reportedly obtained by the local news stations. 

When given a breathalyzer test, Munoz's reading allegedly came back as a .179, which is more than twice the legal limit, according to WFAA. 

Munoz reportedly told the officers he had "one Patron shot in the afternoon,” and had been coming from a Hooters in Grand Prairie before heading to work. He did not pass any of the field sobriety tests given to him, per WFAA.

Before being booked into jail, Munoz reportedly admitted that cocaine was also in his system, also according to WFAA.
