HARRISBURG — Gov. Tom Wolf on Monday nominated a retired state police major to lead the agency two months after the Senate scuttled his first choice for the commissioner’s job.

Tyree Blocker, who retired in 2005 after working his way up through the ranks of the state police for 30 years, would bring a wealth of knowledge about patrols and criminal investigation, including extensive experience in drug enforcement, staff services and administration, the Democratic governor said.

“Major Blocker will build on the strong foundation of the traditions and culture of the Pennsylvania State Police while also looking for opportunities to ensure that the force reflects the diversity of Pennsylvania,” Wolf said.

Blocker, 62, currently owns a fitness company. He’s the second nominee Wolf has proposed as commissioner.

In June, the Republican-controlled Senate rejected Wolf’s nomination of Marcus Brown along nearly straight party lines. Critics cited concerns that included Brown’s decision to wear the police uniform even though he had not gone through the Police Academy and his liberal views on law enforcement. The troopers’ union opposed his nomination, raising doubts about his effectiveness as a leader.

Brown, a former Maryland state police superintendent and a one-time No. 2 officer in the Baltimore Police Department, continues to serve as acting commissioner and plans to stay on during the transition to a new commissioner.

The Pennsylvania State Troopers Association issued a brief statement congratulating Blocker. Senate Republicans were taking a wait-and-see approach, a spokesman said.
