Opinion

COURT OF APPEALS EIGHTH DISTRICT OF TEXAS EL PASO, TEXAS

§ MOSES ALVAREZ, No. 08-11-00160-CR § Appellant, Appeal from § v. 432nd District Court § THE STATE OF TEXAS, of Tarrant County, Texas § Appellee. (TC # 1126294D) §

OPINION

Moses Alvarez appeals a judgment revoking community supervision. For the reasons

that follow, we affirm.

FACTUAL SUMMARY

A Tarrant County grand jury indicted Appellant for the offense of intoxication assault.

See TEX.PENAL CODE ANN. § 49.07 (West 2011). In 2009, he waived his right to a jury trial and

entered a negotiated plea of guilty. In exchange, the State recommended a fine of $1,500 and

imprisonment for ten years, probated for ten years. The trial court accepted the plea, found

Appellant guilty, and assessed his punishment in accordance with all of the terms of the plea

bargain.1

1 Appellant was convicted of intoxication manslaughter and placed on community supervision in a related case. The terms and conditions of community supervision required Appellant to participate in

electronic monitoring. The order required Appellant to have a SCRAM2 device around his ankle

which monitored his transdermal alcohol levels twenty-four hours a day. In December 2010, the

State filed a motion to revoke Appellant’s community supervision based on an allegation that he

had violated this condition by tampering with the SCRAM device on November 4, 5, and 6,

2010. At the revocation hearing, Appellant stipulated that Recovery Healthcare, the company

which operates the program and monitors the SCRAM devices, notified Appellant’s probation

officer that the company had received a “tamper signal” from the device on November 4, 5, and

6, 2010. After conducting a Kelly-Daubert hearing, the trial court determined that Vickers L.

Cunningham, Sr., the chief operating officer of Recovery Healthcare, could testify as an expert

witness on the SCRAM device and interpretation of the data it collected. The trial court

admitted into evidence a report from Recovery Healthcare reflecting that Appellant’s SCRAM

device had been tampered with on those dates. Appellant testified at the hearing and denied

tampering with the SCRAM device. The trial court found the allegations true, revoked

Appellant’s community supervision, and sentenced him to imprisonment for four years.

ADMISSION OF EXPERT TESTIMONY

In Point of Error One, Appellant contends that the trial court abused its discretion by

determining that Vickers L. Cunningham, Sr. was qualified to testify as an expert. Appellant

does not argue that the expert testimony is not reliable or relevant.

Cunningham’s Testimony about the SCRAM Device

Cunningham is the chief operating officer for Recovery Healthcare Corporation. He

previously served as a criminal district judge in Dallas County from 1995 through 2006 and he

was the first Texas judge to use SCRAM when it became available in 2003. Because there was 2 SCRAM is an acronym for Secure Continuous Remote Alcohol Monitor.

-2- no formal training available at that time, he learned about the technology and the device from the

owner and the inventor. After Cunningham left office, he became a principal at Recovery

Healthcare. Cunningham does not have a degree in science or applied science. He has testified

as an expert witness regarding the SCRAM device in both state and federal courts on many

occasions.

Cunningham explained that the SCRAM device is based on a valid scientific theory,

namely, that transdermal elimination of alcohol occurs by any human being who consumes it.

Hundreds of studies have been made since the 1930’s validating this scientific theory.

Approximately 1 percent of the alcohol consumed by a person is eliminated through the

epidermis and the remainder is excreted through the breath and urine. The SCRAM device

measures the alcohol being excreted by the skin by drawing air into the sample chamber where it

goes across the fuel cells and electric current is registered. The device draws the same amount of

air into the chamber each time so it is a relative quantitative analysis. A sample is drawn into the

chamber every thirty minutes so an alcohol absorption and elimination curve can be drawn

allowing Recovery Healthcare to exclude environment stimulants such an a hand sanitizer

containing alcohol.

The device also has anti-tampering measures. First, the device measures temperature to

ensure it is on a person as opposed to being on an inanimate object. Second, the device uses an

infrared sensor to verify that the device has not been obstructed by some object or substance.

Cunningham conducts training for judges, probation officers, prosecutors, and defense lawyers.

During those training sessions, he places a SCRAM device on individuals and demonstrates what

the device can and cannot do. The infrared (IR) sensor is located at the top of the device where

the sample is drawn into the chamber and it shoots a beam of light which bounces off of the skin

-3- and is received back at the device’s IR receiver. The device measures the reflectivity of the skin.

When the device is first placed on the client, the IR sensor establishes an initial baseline reading

for the client. If an individual places anything between the device and the skin in an effort to

tamper with it, the infrared signature measured by the device will be altered. Cunningham

explained that people had tried multiple methods of tampering with the device such as placing

cellophane or chicken skin over the skin near the device but the infrared sensor would detect the

difference in the infrared signature. The device records the transdermal alcohol content, the

temperature, and the IR voltage on an internal flash drive, and transmits the data to Recovery

Healthcare by means of a modem at a designated time each day. The data can also be transferred

from the device manually.

Cunningham testified about State’s Exhibit 5, the report created by Recovery Healthcare

related to the SCRAM device worn by Appellant during the time in question. The report

included a graph depicting the TAC, temperature, and IR voltage over a three-day period

beginning on November 4, 2010 at 6:00 a.m. and concluding at midnight on November 6, 2010.

The IR data showed a significant variance from the baseline and outside of the normal range

beginning on the evening of November 4, 2010 and continuing through November 6, 2010. In

Cunningham’s opinion, the data collected by the device showed that something was placed

between the unit and Appellant’s skin that prevented the device from taking an accurate sample.

Cunningham reviewed the data for a two-week period both before and after the tampering event

and concluded that the device was working properly. Relevant Law and Standard of Review

A trial judge has substantial discretion is determining whether a witness possesses

sufficient qualifications to assist the jury as an expert on a specific topic in a particular case.
