Medford police have arrested a man who they believe slipped into a Progress Drive apartment last week and beat his former girlfriend and her new boyfriend with a golf club while they slept, then jumped out a window to escape.

Officers arrested Donovan David Maxwell, 21, at 11 p.m. Wednesday on a first-degree burglary charge and two counts of second-degree assault. He was lodged in the Jackson County Jail.

Maxwell is suspected of entering an apartment in the 1100 block of Progress Drive at about 2 a.m. April 18 and attacking the sleeping couple — 37-year-old woman and a 23-year-old man — with a golf club, Medford police Detective Sgt. Mike Budreau said.

Awakened by the attack, the pair suffered injuries that required treatment at Rogue Valley Medical Center, but were able to defend themselves.

A roommate heard their shouts and came to their aid, and police were summoned. Maxwell smashed the second-story bedroom window with the golf club, then jumped out and fled. A police dog searched the area, but didn't find him.

Investigators caught up with him Wednesday night at a family member's home in the 100 block of Winema Way, Medford. He was arrested on a warrant issued after an indictment earlier that day in Jackson County Circuit Court. He was arraigned in court Thursday, and remained in jail on $250,000 bail.
