We don't know as he quickly disappeared from the official record after doing this. If you go to CE-2554 (a synopsis of his actions on 11/22/63) you will see on the second page at the bottom, Special Agent Howard stated that a SUSPECT had been captured by Ft. Worth police and that he wished me to accompany him to Ft. Worth to question the suspect.? (Emphasis added) He reported this and was given permission to depart. http://historymatters.com/archive/jfk/wc/wcvols/wh25/html/WC_Vol25_0409a.htm
The ONLY other mention of this suspect is found in CE-705 on page 380 when it says:
44 ? DD 4857. Subject in green and white Ford 1957, apprehended in Ft. Worth. Not sure at this time whether or not him, but was apprehended in Tarrant County.
Actually, that license # probably should have been D
T 4857 not DD

https://www.maryferrell.org/showDoc.html?docId=48754#relPageId=7&tab=pageIt seems that the tale Mr House gave the authorities was that he drove some 100 miles to Dallas to visit a friend...didn't call first...just decided to show up.
Well his friend wasn't home [perhaps on Belmont Ave] so Mr House thought he would go downtown and see the motorcade. After that he decided to just drove on back home. He didn't even try to contact the friend he came to visit.
It seems that Mr House had more closely matched the broadcast description of the assassination suspect than Oswald did. And that [or a tip of some sort] + a license plate search got Mr House picked up by the Fort Worth Police. Seem strange? Read the rest...
