16-10654 Opinion of the Court 3
Thomas Mitchell Overton, who is incarcerated on death
row in Florida, appeals the district court’s denial of his 28 U.S.C.
§ 2254 petition for a writ of habeas corpus. This appeal concerns
whether his petition was timely filed. It also concerns his claims
that trial counsel was ineffective in failing to prepare for and partic-
ipate adequately in a preliminary hearing and that the State vio-
lated Brady v. Maryland 1 by failing to disclose an investigator’s his-
tory of sloppy evidence collection practices. After a thorough re-
view of the record and with the benefit of oral argument, we con-
clude that Overton’s petition was timely, but that it was properly
denied in the alternative on the merits. We therefore affirm the
judgment of the district court. 2
I. BACKGROUND
In this section, we discuss the crimes of which Overton was
convicted and the investigation of these crimes before turning to
examine the relevant pretrial proceedings, the trial, and the post-
conviction proceedings.
A. The Murders and Law Enforcement’s Investigation
The crime scene that confronted investigators was re-
counted by the Florida Supreme Court as follows (edited here for
brevity):
1 Brady v. Maryland, 373 U.S. 83 (1963).
2 Overton’s motion to supplement the record on appeal, which we carried
with the case, is DENIED. See Cullen v. Pinholster, 563 U.S. 170 (2011).

4 Opinion of the Court 16-10654
On August 22, 1991, Susan Michelle MacIvor, age 29,
and her husband, Michael MacIvor, age 30, were
found murdered in their home in Tavernier Key. Su-
san was eight months pregnant at the time with the
couple’s first child.
....
Once law enforcement officers arrived, a thorough
examination of the house was undertaken. In the liv-
ing room, where Michael’s body was found, investiga-
tors noted that his entire head had been taped with
masking tape, with the exception of his nose which
was partially exposed. . . . The investigators surmised
that a struggle had taken place because personal pa-
