OLATHE, Kan. (AP) — The Johnson County sheriff says federal immigration authorities have placed a detainer on the man charged in the death of sheriff’s deputy killed when a pickup slammed into his patrol car during a traffic stop.

Adrian Espinosa-Flores, of Kansas City, Kansas, is being held in Johnson County on $2 million bond after being charged Monday with involuntary manslaughter/DUI in the death Sunday of Master Deputy Brandon Collins. Collins was making a traffic stop at the time.

Sheriff Frank Denning said Tuesday that U.S. Immigration and Customs Enforcement placed a detainer on Espinosa-Flores.

Denning says the detainer is a request to local law enforcement agencies to hold a person for possible deportation once they’ve gone through the court system. Denning says the detainer also means Espinosa-Flores won’t be released on bond.
