LAS CRUCES – Former Santa Fe County deputy Tai Chan likely had a blood-alcohol level three times the legal limit for driving when he fatally shot his colleague in 2014, a psychologist who is an expert on alcohol and energy drink consumption testified Thursday during the retrial for Chan.

Cecile Marczinski, a psychologist from Northern Kentucky University, told jurors Thursday that by using receipts and witness statements, she gauged how much alcohol Chan likely consumed at five restaurants and bars the evening of Oct. 27, 2014, prior to the shooting. She plugged that information, along with an estimate of Chan’s body weight, into an accepted scientific formula for calculating intoxication levels.

  ‘Grossly intoxicated’

Marczinski said she concluded Chan likely had a blood-alcohol level of 0.24 grams per 100 milliliters — three times the legal limit for driving.

“So you can assume this person is grossly intoxicated at the time of the shooting,” she said.

Chan’s blood-alcohol limit wasn’t tested the night of the shooting, which is why Marczinski, an expert for the defense, was called to testify.
