Boy born 2-5-70 looking for birth family

I have more info since my last post. Time of birth was 9:11 p.m. at St. Luke's Hospital in denver. Appears to be an imediate adoption by the dates on the birth certificate. There is one date that does not match and shows Feb. 3rd for date signed for witness, but I think it is a typo due to date and hour of birth and all other dates being the 5th. Thanks for any info.
