CHICAGO — A 23-year-old man has been charged with a home invasion early Saturday that targeted a couple ages 84 and 81, police said Monday.

At 9:30 a.m. Saturday, police officers in the 4700 block of West Barry Avenue saw Christopher Perez, 23, "acting suspiciously," police said. Perez ducked behind a car and tossed a black object on the ground, which the officers later discovered to be a pouch full of jewelry, police said.

Believing the jewelry to be stolen, the officers started to arrest Perez, of the 4800 block of West Fletcher Street, but he resisted.

The jewelry later was confirmed to be from a home invasion earlier that day in the 5800 block of West Wellington Avenue, and Perez was identified as the man who broke into the home, police said.

He was charged with two counts of home invasion with a dangerous weapon, one count of resisting arrest and one count of theft. He also was wanted for a parole violation, police said.

He was scheduled to appear in bond court Monday.

Records from the Illinois Department of Corrections show Perez was released from prison in May 2016. He had been sentenced to 5½ years in prison for a 2014 case for burglary and possession of stolen guns. He previously was sentenced to 3 years in prison for a 2011 robbery case.

On Saturday, Supt. Eddie Johnson said police believed three of the four recent home invasions on the Northwest Side were related, though police had no further information Monday on whether Perez was a suspect in any of the other crimes.

On Thursday night, an elderly couple was attacked and robbed in their Portage Park home. On May 19, a 78-year-old woman was badly beaten and robbed by a man while she cleaned her Irving Park home. Another attack occurred Tuesday night in the 4800 block of West Nelson Street, police said.

In the Wellington Avenue home invasion, a man climbed into the couple's home through a back window at 1:19 a.m. He walked up to the 84-year-old man in the living room and said he had a gun.

The man and woman gave the thief a wallet, checkbook, $30 in cash and jewelry, police said.
