We propose an alternative interpretation of the top events discovered at the Fermilab Tevatron in 1995. Given that the charge of the {ital b} quark jet cannot be measured for the whole sample with certainty, the signal can be due to a quark of charge {minus}4/3 at the reported mass, i.e., 174 GeV, while the top quark is actually heavier, say above 230 GeV. We point out in this paper that such a scenario is actually hinted at by the latest precision electroweak measurements of {ital Z} decay. To rule out this possibility in the future, the {ital b} quark jet charge analysis has to become definitive, or the single {open_quotes}top{close_quotes} production cross section has to be measured. {copyright} {ital 1999} {ital The American Physical Society}
