CEDAR RAPIDS — Jerome Power will spend the rest of his life in prison for strangling to death his neighbor Doris Bevins, 68, in 2010.

A Linn County jury found Power, 50, of Cedar Rapids, guilty of first-degree murder Tuesday after deliberating for about a day and a half. The trial lasted four and a half days.

Power looked down, shook his head and looked up again after the guilty verdict was read. He was shackled Tuesday after throwing a cup of water on one of his attorneys Monday, and had a mild outburst early Tuesday. The judge warned Power that if he didn’t behave, she would remove him from court.

Jurors at one point Tuesday sent a note to the judge saying they were deadlocked. The judge urged them to continue deliberating, and the jury reached a unanimous verdict about four hours later.

Earlier, jurors had asked about the 911 call to police, wondering if Bevins was on the phone with her friend Philip Bemer as she was attacked, and what time Bemer called 911.

The attorneys and judge sent a note back saying all the evidence has been submitted and they could not give further information.

Bemer testified he called 911 as soon as he overheard Bevins screaming and telling someone to “get out” Sept. 19, 2010. Cedar Rapids Police Officer Sarah Lacina testified she was the first one on the scene and got there about 45 seconds after the 911 call.

When police arrived, the door was deadbolted and after trying to kick it in, police said they had to break a window to get inside. They found Power inside hiding by an entry door, according to testimony.

Bevins was found lying on the floor unconscious with pajama pants tightly tied around her neck, according to testimony. She died the next day. The cause of death was ligature strangulation.

Update:: The jury in the Jerome Power first-degree murder trial sent a note to the judge Tuesday afternoon, saying they couldn’t reach a unanimous verdict.

Jason Dunn, Power’s attorney, said considering they have deliberated for more than nine hours, he asked for a mistrial.

Linn County Attorney Jerry Vander Sanden said he didn’t think they had deliberated an “extraordinarily” long amount of time. He asked the judge to have them continue to deliberate.

Sixth Judicial District Fae Hoover-Grinde said she estimated the jury had deliberated 9-1/2 to 10 hours, and she didn’t think that was a extraordinarily long time to deliberate. She said she was going to send them a note, urging them to continue deliberations in a attempt to reach an unanimous verdict.

Earlier update: The jury continues to deliberate in the murder trial of Jerome Power, 50, who is accused of strangling to death his neighbor Doris Bevins, 68, in 2010.

The jurors just had two questions, regarding what time Bevins was talking on the phone with her friend Philip Bemer as she was attacked, and what time Bemer called 911 to report it.

The attorneys and judge sent a note back saying all the evidence has been submitted and they can’t give further information.

Bemer testified he called 911 as soon as he overheard Bevins screaming and telling someone to “get out.”

Cedar Rapids Police Officer Sarah Lacina testified she was the first one on the scene and she got there about 45 seconds after the 911 call came in.

The jurors may be attempting to determine if someone else had time to leave the residence before police arrived, as Power claimed.

Power said he didn’t kill Bevins and blamed the crime on two other men.

Police testified the two others Power accused were investigated and neither were ever suspects in this crime.

Bevins was found by police Sept. 19, 2010 unconscious lying on the floor with pajama pants tightly tied around her neck, according to testimony. She died the next day. The cause of death was ligature strangulation.

Power was inside hiding by an entry door when police had to break a window to get into the locked apartment, according to testimony. Police testified they shouted repeatedly, pounded on the door and even kicked for about four minutes it in an attempt to get in the deadbolt locked door. Power didn’t let them inside.

Power is charged with first-degree murder. If convicted he faces life in prison without parole.

He was found hiding inside behind an entry door by police when they had to break a window to gain access into the locked apartment, according to testimony.

Power said he didn’t kill Bevins and claimed two different men killed her, according to testimony.
