OLATHE, Kan. — A man charged in a crash that killed a Kansas deputy could face eventual deportation proceedings because of suspected immigration violations and a previous drunken driving conviction in California, according to U.S. Immigration and Customs Enforcement.

Adrian Espinosa-Flores, 38, of Kansas City, Kansas, is being held in the Johnson County jail on $2 million bond after being charged with involuntary manslaughter/DUI in the crash that killed Johnson County Sheriff’s Master Deputy Brandon Collins. Collins, 45, was making a traffic stop Sunday when a pickup hit his stopped patrol car.

The public defender for Espinosa-Flores didn’t immediately return a call Wednesday.

U.S. Immigration and Customs Enforcement placed a detainer on Espinosa-Flores on Monday, ICE spokesman Shawn Neudauer said in an email late Tuesday. The detainer means that if local authorities release Espinosa-Flores for any reason, ICE asks that they release him into ICE custody.

A 2001 DUI conviction in California also makes Espinosa-Flores an ICE enforcement priority, which means he would face deportation proceedings, Neudauer said. He could not comment on Espinosa-Flores’ immigration status, which is considered private. But ICE said it only places detainers on people suspected of immigration violations.

Espinosa-Flores was also stopped in Overland Park, Kansas, in June 2013 for speeding and driving without a valid driver’s license, according to the Overland Park municipal court. He paid about $280 in fines and fees.

ICE was not notified by authorities in California or Kansas of either arrest, Neudauer said.

He said ICE would prefer that “justice is done locally,” and the agency doesn’t have “any interest in interrupting” local court proceedings.
