OAKLAND TWP — Police continue to search today for a man wanted for shooting his girlfriend during a weekend domestic dispute.

For two days, police in Butler County have searched woods, neighborhoods and other would-be hiding spots for 49-year-old Robert Amend from Pittsburgh's Sheraden.

For two days, they've come up empty handed.

“He could be anywhere,” state police Lt. Chris Yanoff said Sunday, which came and went without a trace of the wanted man. “We're still assuming he's in the area.”

State police patrols will be out again today in and around Oakland Township where Amend evaded pursuing troopers during a brief high-speed chase on Route 68 Saturday morning.

Pittsburgh police were looking for Amend on charges he shot his estranged girlfriend earlier that day at her apartment in the city's Crafton Heights neighborhood.

The 40-year-old woman was shot in a leg and her side but is expected to recover, authorities said.

Amend made his getaway into Butler County by turning off Route 68 west just past the Oakland Township Elementary School after his car ran over a spike strip that police had laid on the road.

His car went down an embankment and into a trailer park. He got out and fled on foot through woods shortly before noon.

An extensive nine-hour search by Pittsburgh police and state police Saturday was unsuccessful.

A “passive search,” as Yanoff called it, using roving patrols, was employed Sunday with similar results. The same tactics will used today.

“You have to overturn every rock and that's what we're doing,” Yanoff said. “We want to catch this guy before he hurts anyone else.”

Police urge residents to be on alert and call 911 if they see Amend. They caution that he is likely armed.
